JEDEC Solid State Technology Association today announced the publication of JESD209-5A, Low Power Double Data Rate 5 (LPDDR5).
LPDDR5 will eventually operate at an I/O rate of 6400 MT/s, 50% higher than that of the first version of LPDDR4, and will significantly boost memory speed and efficiency for a variety of applications including mobile computing devices such as smartphones, tablets, and ultra-thin notebooks. This update to the LPDDR5 standard is focused on improving performance, power and flexibility. Additional timing parameters and minor editorial corrections have also been included.
Developed by JEDEC’s JC-42.6 Subcommittee for Low Power Memories, JESD209-5A is available for download from the JEDEC website.
Key updates to this latest version of the specification include:
- Additional power reduction functions including WCK power reduction
- Optimized Refresh
- Data/Byte selectable Write X
- Additional SI improvements
- ODT Rank to Rank turnaround improvement
- ODT function for CS pin
- Pin capacitance decrease
