Erase Suspend / Erase Resume

The Erase Suspend command allows the system to interrupt a sector erase operation and then read data from, or program data to,

the main flash array. This command is valid only during sector erase or program operation. The Erase Suspend command is ignored

if written during the chip erase operation.

When the Erase Suspend command is written during the sector erase operation, the device requires a maximum of tESL (erase

suspend latency) to suspend the erase operation and update the status bits.

After the erase operation has been suspended, the part enters the erase-suspend mode. The system can read data from or program

data to the main flash array. Reading at any address within erase-suspended sectors produces undetermined data. The system can

determine if a sector is actively erasing or is erase-suspended by reading the Status Register or using Data Polling. Refer to Status

After an erase-suspended program operation is complete, the EAC returns to the erase-suspend state. The system can determine

the status of the program operation by reading the Status Register, just as in the standard program operation.

If a program failure occurs during erase suspend the Clear or Reset commands will return the device to the erase suspended state.

Erase will need to be resumed and completed before again trying to program the memory array.

Accesses and commands that are valid during Erase Suspend are:



Read to any other non-suspended sector



Program to any other non-suspended sector



Status Register Read



Status Register Clear



Enter DYB ASO



DYB Set



DYB Clear



DYB Status Read



Exit ASO or Command Set Exit



Erase Resume command

To resume the sector erase operation, the system must write the Erase Resume command. The device will revert to erasing and the

status bits will be updated. Further writes of the Resume command are ignored. Another Erase Suspend command can be written

after the chip has resumed erasing.

Erase suspend and resume is not supported while entered in an ASO. While in erase suspend entry into ASO is not supported.
