Q0810B

consideration for both ISP and RDT FW)
11. Issue Fix: Rest data in HW front-end buffer may
cause the BVA halt from releasing SATA engine.
12. Issue Fix: Sanitize frozen status should lock sanitize
feature commands only.
13. Issue Fix: HDMA count may overflow during closing
part read FIFOs.
14. Issue Fix: Apply DEVSLP after Slumber ACK
Immediately would cause drive hang on DIPM Flow.
15. Issue Fix: An error NCQ (double tag or out of range
LBa … etc) came during standby mode, FW should
not return D2H in ISR.
16. Issue Fix: For read retry sequence of Toshiba
24nm/32nm SLC NANDs, 26h command should be

21. Issue Fix: For Micron L06B 2TB drive, FW reports “too
much bad” without default capacity setting during pretest
flow.
22. Issue Fix: As program fail handle is disabled, minimum
size of cache buffer(for host data) should be 3.5*size of
super page, to prevent dram buffer flag issue.
23. Issue Fix: FW may refer to bit 0 of status register to
check cache status.
24. Issue Fix: During sata error handle sequence, HW BVA
reset may stop HDMA data transfer.
25. Issue Fix: Check HW command queue done before
applying set feature sequence to NAND flash.
P1225C
Q0113B
P1225C
This FW supports both 2D/3D MLC NAND (does not feature
SLC caching)
26. Support Micron L06B 2TB capacity.
27. Reduce command latency as GC is under operation.
28. Add one check spare seed mode to detect any plane
“ALL FFh” pattern output.
(in check EOB of Tail block or build F2H Map for unfull
block)
29. Avoid specific L06B Train ADJ Fail in MP Flow. (Bit flip
of parity of spare data)
30. Add vendor unique command for VPX to perform
external destroy.
31. Add customized erase unit function for VPX.
32. Add MP option, if RDT Fail, keep ALL block program
state, Don’t Erase. (UFD Sorting)
33. Issue fix: As program fail handle is disabled, minimum
size of cache buffer(for host data) should be 3*size of
super page, to prevent dram buffer flag issue.
34. Issue Fix: Modify the cases that FW would clear
SM2246EN F/W Release Note
[ 4 ] 9/1/2017
following commands as LSCS occurs.
35. Issue Fix: As enable/disable write cache is set by SCT
command, the feature can not be changed by set
feature command. Device should not return error as
well.
36. Issue Fix: Initialize Link Table Info entirely in Erase Unit,
in case that misplaced Link Table Info might be saved
afterward.
37. Issue Fix: Save security info prior to Prepare Fast Boot
procedure before entering DEVSLP to keep fast boot ID
for Link Block.
38. Issue Fix: Variable overload leads to FW return wrong
status.
P1111A
P1125A
P1111A
This FW supports both 2D/3D MLC NAND (no SLC caching)
1. Update SecurityFW to version: SMI_SEC_SATA_P1027A.
2. Update RDT to version P1027RDT: Modify that FW would
output all FFh pattern in MP “Self Test Result” list for L06B

specific NANDs.
4. For different type of SanDisk 1znm NAND, corresponding

case: all FFh pattern output by any plane.
8. Add pretest error code 0x28: CannotFindSysBlk to indicate
number of bad block in each slot.

should not return error status as host apply disable write
cache.

5. Add Lower Page Protection (LPP) for I/M L06B 3.3V
devices.
