operation using the DQ7 or DQ6 status bits, just as in the standard Byte Program
operation. Refer to the "Write Operation Status" section section for more
information.
In the erase-suspend-read mode, the system can also issue the autoselect com-
mand sequence. The device allows reading autoselect codes even at addresses
within erasing sectors, since the codes are not stored in the memory array. When
the device exits the autoselect mode, the device reverts to the Erase Suspend
mode, and is ready for another valid operation. Refer to the "Autoselect Mode"
To resume the sector erase operation, the system must write the Erase Resume
command. The bank address of the erase-suspended bank is required when writ-
ing this command. Further writes of the Resume command are ignored. Another
Erase Suspend command can be written after the chip has resumed erasing.
Table 11. S29JL064H Command Definitions
Legend:
X = Don’t care
RA = Address of the memory location to be read.
RD = Data read from location RA during read operation.
PA = Address of the memory location to be programmed. Addresses latch on the falling edge of the WE# or CE# pulse,
whichever happens later.
PD = Data to be programmed at location PA. Data latches on the rising edge of WE# or CE# pulse, whichever happens
first.
SA = Address of the sector to be verified (in autoselect mode) or erased. Address bits A21–A12 uniquely select any
sector. Refer to Table 3 for information on sector addresses.
BA = Address of the bank that is being switched to autoselect mode, is in bypass mode, or is being erased. A21–A19
uniquely select a bank.
