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

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
