Hi Robert,
I got some feedback from Kingston regarding EMMC pSLC configuration, I thought you might be interested in the info. I would like to share it with you.
( the Jesd84-B51.pdf too large to upload)
EMMC16G-TB29-90F01 is standard configuration chip P/N
EMMC16G-TB29-90F02 is pSLC configuration chip P/N
- EMMC Chip with EMMC16G-TB29-90F01 is in standard configuration ONLY?
This is the standard configuration. Standard configurations can be set to pSLC mode which is a one-time-programmable (OTP) operation and cannot be undone. All data is lost when converting to pSLC.
EMMC16G-TB29-90F01
eMMC 5.1
Standard Temp. -25C to +85C
Package 11.5 x 13.0 x 0.8 mm
Native 3D TLC NAND Flash
Sector count 30,621,696 = 30,621,696 * 512 = 15,678,308,352 Bytes
- EMMC Chip with EMMC16G-TB29-90F02 is in pSLC as default? Is it possible to be re-partitioned as mixed ( some as standard, and some as pSLC) ?
This part is set as pSLC mode from the factory. Standard configured parts can be set to have a mix of standard and pSLC sections. Once set in pSLC it cannot be undone due to the OTP nature.
Section “6.2.4 Configure partitions” of the JEDEC standard (attached) describes how to set pSLC which they call “Enhanced User Data Area”.
EMMC16G-TB29-90F02
eMMC 5.1
Standard Temp. -25C to +85C
Package 11.5 x 13.0 x 0.8 mm
Native 3D TLC NAND Flash converted to pSLC.
Sector count 10,207,232 = 10,207,232 * 512 = 5,226,102,784 Bytes
Best Regards,
