BLOCK ERASE Operation
Address Input (3 Cycles)
Erasing occurs at the block level. For example, the MT29F2G08xxB device has 2,048
erase blocks organized as 64 2,112-byte (2,048 + 64 bytes) pages per block. Each block is
132K bytes (128K + 4K bytes). The BLOCK ERASE command operates on one block at a
time. (See Figure 28.)
Three cycles of addresses A[28:18] are required for the x8 device, and three cycles of
addresses [27:17] are required for the x16 device. Although addresses A[17:12] (x8) and
A[16:11] (x16) are loaded, they are a “Don’t Care” and are ignored for BLOCK ERASE
operations. (See Figures 5 and 6 on page 11 for addressing details.)
The actual command sequence is a two-step process. The ERASE SETUP (60h) com-
mand is first written to the command register. Then three cycles of addresses are written
to the device. Next, the ERASE CONFIRM (D0h) command is written to the command
register. At the rising edge of WE#, R/B# goes LOW and the internal write state machine
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 Figure 28, and Table 9 on page 28.)
