SSD

• Status:– JC64 has decided to form JC64.8 SSD committee at Aug.’07, but will work

with other standard groups first to determine the optimal means for JEDEC to work, in a cohesive manner with existing standards group(s).

• Scope: Under discussion– Will be finalized after surveying industry standardization status

• Possible area of cooperation with T13– Co-define Identification and command set for NAND-based storage device

which in some portion T13 is already doing– There might be some other areas JEDEC can help industry, for example

common board design (guide), mechanical spec definition

• Discussion

UFS (Universal Flash Storage)

• Scope: – Define next generation removable & embedded storage device specification.– Raw speed target of ~300MB/s per data lane with future scalability

• Status:– UFS TG formed at JEDEC (Dec. ’07)– Over 46 companies have participated

• Various Industries from memory, chipset, mobile phone makers and more

• Possible area of cooperation with T13– Command set definition, which will primarily be used for removable & embedded

storage devices, but may also be compatible with ATA spec

• Discussion
