To cater to ever-increasing bandwidth demands from low-power DRAMs especially for devices like cell phones, tablets and others with limited power budgets, JEDEC has extended the clock frequencies supported by its latest low power memory offering LPDDR5 to include the 937MHz and 1066MHz that translates to the max data rates of 7500MT/s and 8533 MT/s.
Devices supporting these incredibly high data rates are being categorized as LPDDR5X SDRAM devices. To support these high speeds whiles still keeping the real DRAM hardware complexity in check, lot of work has been done by JEDEC member companies including Cadence as an active JEDEC member.
Here is the list of key differences that LPDDR5X SDRAM devices have over LPDDR5 SDRAM:
Overall LPDDR5X SDRAM is one of the fastest DRAM memories supported currently with Data rates of 8533 MT/s.
Cadence MMAV VIPs for LPDDR5 and LPDDR5X are compressive VIP solutions and support all of the above-listed LPDDR5X features. LPDDR5X is still being worked upon so we may see additional features being added to it in 2021 and Cadence is actively tracking the development of the LPDDR5X standard at JEDEC.
More information on Cadence LPDDR5 VIP is available at the Cadence VIP Memory Models Website.
