  • SoC and IP: Storage Analyst Jim Handy says “NAND Cache is Back!”

    archive
    archive
    Storage analyst and Grand Poobah Jim Handy has just released a free White Paper titled “NAND Cache is Back: SSD Performance at an HDD Price” and it’s worth a look if you are interested in either the market for NAND Flash or have any interest in PC and server storage. The reason this White Paper is worth a look is because Handy goes into substantial quantitative detail with extensive graphs in his analysis and mapping…

    Earlier, this blog reported on OCZ’s Enyo USB 3.0 SSD and now at a private event held at this week’s Computex show in Taiwan, memory vendor Kingston has shown a prototype USB 3.0 SSD (as reported by Tom’s Hardware and Softpedia). Slated for August availability, the HyperX SSD will reportedly be offered in capacities of 64, 128, and 256 Gbytes. The USB 3.0 connection gives the drive peak read and write speeds of 195 and…

    PC add-on vendor OCZ plays in several high-performance PC component markets including DRAMs and SSDs. The company is at the Computex 2010 event in Taiwan this week and is reportedly introducing a high-performance SSD on a PCIe x4 plug-in card. Anandtech’s coverage of the introduction reports that the RevoDrive is based on a pair of Sandforce SF-1200 controller chips in a RAID configuration. (The photo on the Anandtech…

  • SoC and IP: Hitachi’s Z HDDs: Will 2.5mm less height make a difference? For SSDs?

    archive

    Hitachi just shaved 2.5mm off of the top of its 2.5-inch laptop hard drives, producing a line of 5400- and 7200-rpm, single-platter HDDs called the Z series (Z is the height axis, get it?) with capacities of 160 to 320 Gbytes. (Press release here.) Although there are standard specs for a 2.5-inch drive’s width and depth, height is not part of the size spec but some heights have become de facto standards. Initially, 2…

    As discussed last week in this blog, Hitachi-LG Data Storage (HLDS)--an OEM vendor of optical drives that’s a joint venture between Hitachi and LG--introduced a combo optical/solid-state drive called HyDrive last week at Computex 2010 in Taipei with a few more technical details about the drive. (See: How does a hybrid SSD/optical drive make sense?) The initial version of the HyDrive will reportedly be based on a DVD burner…

    A few days ago, this blog discussed the “big resistor” model of SDRAM power consumption (see Marc Greenberg’s “big resistor” model of semiconductor DRAM power consumption) and that blog entry ended with this statement:

    “It might also be a very good idea to design your system so that it can accommodate more than one DDR variant. That way, time and circumstance can determine which DRAM technology gets used at any given…

    Some combinations like chocolate with peanut butter, ice cream with peanuts and chocolate sauce, and HDDs with NAND Flash caching make obvious sense. Other combinations don’t make such an obvious match. In these cases, people need extra convincing. LG and Hitachi are suggesting just such a non-obvious combo as a concept: an optical drive and NAND Flash. Optical drives? Aren’t they on the way out, like floppy disks? Not…

    I checked my Linked-In messages the other day and saw a survey by Girish Patil with the provocative question "Is EDA360 the same experiment that Phoenix Technology tried a decade ago with the acquisition of Virtual Chips and Sand Micro?" Well, that was an interesting link between my past professional life and my role at Cadence today.

    Phoenix Technologies was -- and remains -- a leading provider of BIOS for…

    Too many DRAM choices. If you want low power DRAM, do you choose LPDDR1, LPDDR2, DDR2L, DDR3L, or what? It’s not an easy choice because of all the variables involved: the peak and average transfer rates, the power supply voltages, and the IC manufacturing process technology used--just to name three. In addition there are the DRAMs’ various operating modes and the corresponding current consumption in each mode. The modes…

    Earlier, we covered the announcement of OCZ’s Enyo USB 3.0 external SSD. Now PC Perspective has created a pretty interesting video review of the drive. OK, the review starts kind of slow and seems to have very little technical meat but you might want to let the video play until they disassemble the drive to reveal the product’s interesting silicon guts. That’s when you’ll learn all you need to know about the chips inside…

    Can you spare nine minutes to get a really good grounding in SSD concepts? No? How about eight minutes and forty-two seconds? Ah, now we’re talking. Information Week and with Storage Switzerland’s Lead Analyst George Crump have produced an excellent 4-part video tutorial series on SSDs. Each part runs less than 10 minutes and Part 1 covers the technical side of storage evolution in a concise and interesting way that’s…

    Jerry GenPart
    Jerry GenPart

    The SPB16.3 release of Allegro Design Entry CIS (Capture) now allows you to browse power pins in your design. In Capture, most of the design’s power pins are invisible, which makes it difficult to find power pins. The new "browse power pins" capability will help you find the pins faster and increase your productivity.

    In Capture, power and ground supply pins are referred to generically as "power pins."…

  • SoC and IP: Squeeze bandwidth inefficiencies out of DDR DRAMs in memory subsystem designs

    archive

    This blog starts with a simple, sad truth: DDR DRAMs are naturally inefficient. If this statement bothers you, just get over it. All human-made artifacts have inefficiencies and DRAMs are no different. However, there are things you can do to squeeze every bit of bandwidth efficiency out of a DDR DRAM and your efforts can be rewarded with significant performance gains. You can improve memory-subsystem bandwidth by 20-30…

  • Digital Design: Mixed Signal: Why The Sudden Attention?

    PeteMc

    With DAC 2010 rapidly approaching, we can again expect that lots of EDA and IP vendors will use “mixed signal” somewhere in their company’s messaging. Last year it seemed that nearly everyone wanted to jump on the mixed signal “bandwagon” … so what caused this sudden jump in interest in mixed signal?

    We all know that mixed signal design is not new. It’s been around for about 20 years (give or take), but there has…

  • SoC and IP: Why is it so difficult to interface with DRAMs?

    archive
    archive
    One of the maxims in the world of system design is that it has always been relatively hard to interface with DRAMs and make them work properly in all possible operational situations. This isn’t a new situation. It’s been hard to interface with DRAMs since the day they were first introduced back in October, 1970 when Intel rolled out the first commercial DRAM, the 1-kbit 1103. Intel’s 1103 DRAM was a PMOS chip that introduced…

    In my last blog, I took a look back at the history of how we got to the first delivery of UVM. Now, let's take a look forward.  Over the past week since UVM was released, and Cadence opened the UVMWorld portal to support the new UVM Community and ecosystem, I have seen a number of customers asking questions about when to move to UVM as well as the future of OVM and VMM.   Since my team has been developing the OVM over…

If you have anything to do with semiconductor memory--use it, make it, design with it, buy it, dream about it, etc--get out your calendar and reserve July 28 because that’s when MemCon 2010 takes place here in Silicon Valley. Although we’re not quite ready to post the agenda (real soon now, possibly as soon as next week…
