PROGRAM/ERASE SUSPEND Command  
To initiate the PROGRAM/ERASE SUSPEND command, S# is driven LOW. The com-  
mand code is input on DQ0. The operation is terminated by the PROGRAM/ERASE RE-  
SUME command.  
PROGRAM/ERASE SUSPEND command enables the memory controller to interrupt  
and suspend an array PROGRAM or ERASE operation within the program/erase latency.  
If a SUSPEND command is issued during a PROGRAM operation, then the flag status  
register bit 2 is set to 1. After erase/program latency time, the flag status register bit 7 is  
also set to 1, but the device is considered in suspended state once bit 7 of the flag status  
register outputs 1 with at least one byte output. In the suspended state, the device is  
waiting for any operation. (See the Operations Allowed/Disallowed During Device  
States table.)  
If a SUSPEND command is issued during an ERASE operation, then the flag status regis-  
ter bit 6 is set to 1. After erase/program latency time, the flag status register bit 7 is also  
set to 1, but the device is considered in suspended state once bit 7 of the flag status reg-  
ister outputs 1 with at least one byte output. In the suspended state, the device is wait-  
ing for any operation. (See the Operations Allowed/Disallowed During Device States ta-  
ble.)  
If the time remaining to complete the operation is less than the suspend latency, the de-  
vice completes the operation and clears the flag status register bits 2 or 6, as applicable.  
Because the suspend state is volatile, if there is a power cycle, the suspend state infor-  
mation is lost and the flag status register powers up as 80h.  
During an ERASE SUSPEND operation, a PROGRAM or READ operation is possible in  
any sector except the one in a suspended state. Reading from a sector that is in a sus-  
pended state will output indeterminate data. The device ignores a PROGRAM com-
