SUSPEND/RESUME Operations  
SUSPEND/RESUME Operations  
PROGRAM/ERASE SUSPEND Operations  
A PROGRAM/ERASE SUSPEND command enables the memory controller to interrupt  
and suspend an array PROGRAM or ERASE operation within the program/erase latency.  
To initiate the command, S# is driven LOW, and the command code is input on DQn.  
The operation is terminated by the PROGRAM/ERASE RESUME command.  
For a PROGRAM SUSPEND, the flag status register bit 2 is set to 1. For an ERASE SUS-  
PEND, the flag status register bit 6 is set to 1.  
After an 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 oper-  
ation.  
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.  
It is possible to nest a PROGRAM/ERASE SUSPEND operation inside a PROGRAM/  
ERASE SUSPEND operation just once. Issue an ERASE command and suspend it. Then  
issue a PROGRAM command and suspend it also. With the two operations suspended,  
the next PROGRAM/ERASE RESUME command resumes the latter operation, and a sec-  
ond PROGRAM/ERASE RESUME command resumes the former (or first) operation.  
PROGRAM/ERASE RESUME Operations  
A PROGRAM/ERASE RESUME operation terminates the PROGRAM/ERASE RESUME  
command. To initiate the command, S# is driven LOW, and the command code is input  
on DQn. The operation is terminated by driving S# HIGH.  
Table 31: SUSPEND/RESUME Operations  
Operation Name  
Description/Conditions  
PROGRAM SUSPEND (75h)  
A READ operation is possible in any page except the one in a suspended state. Reading  
from a sector that is in a suspended state will output indeterminate data.  
ERASE SUSPEND (75h)  
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 suspended state will output indeterminate data.  
During a SUSPEND SUBSECTOR ERASE operation, reading an address in the sector that  
contains the suspended subsector could output indeterminate data.  
The device ignores a PROGRAM command to a sector that is in an erase suspend state; it  
also sets the flag status register bit 4 to 1 (program failure/protection error) and leaves  
the write enable latch bit unchanged.  
When the ERASE resumes, it does not check the new lock status of the WRITE VOLATILE  
LOCK BITS command.
