Erasing occurs at the block level. The MT29F1G08 and the MT29F1G16 have 1,024 erase
blocks organized as 64 pages per block. The BLOCK ERASE command operates on one
block at a time (see Figure 24).
Two cycles of addresses BA[15:6] are required for the x8 device, and 2 cycles of BA[15:6]
for the x16 device. Although addresses PA[5:0] (x8) and PA[5:0] (x16) are loaded, they are a
“Don’t Care” and are ignored for BLOCK ERASE operations. See Figures 6 and 7 on pages 14
and 15 for addressing details.
The actual BLOCK ERASE command sequence is a two-step process. First, write the
ERASE SETUP (60h) command to the command register. Then write 2 cycles of
addresses to the device. Next, write the ERASE CONFIRM (D0h) command to the com-
mand register. At the rising edge of WE#, R/B# goes LOW and the internal control logic
automatically controls the timing and erase-verify operations. R/B# stays LOW for the
entire
The READ STATUS REGISTER command can be used to check the status of the ERASE
operation. When bit 6 = 1, the ERASE operation is complete. Bit 0 indicates a pass/fail
condition where 0 = pass. See BLOCK ERASE, and Table 9 on page 29 for details.
