Erase aborts if Reset turns to V
operation is aborted, the block must be erased again.
During erase operations the memory will accept the Read Status Register command and
the Program/Erase Suspend command, all other commands will be ignored. Typical Erase
times are given in

using the Erase command.
Program command
The memory array can be programmed word-by-word. Two bus write cycles are required to
issue the Program command:
During program operations the memory will accept the Read Status Register command and
the Program/Erase Suspend command. Typical Program times are given in
Program, Erase times and Program/Erase endurance
Programming aborts if Reset goes to V
program operation is aborted, the block containing the memory location must be erased and
reprogrammed.
See
the Program command.
Double Word Program command
This feature is offered to improve the programming throughput, writing a page of two
adjacent words in parallel.The two words must differ only for the address A0. Programming
should not be attempted when V
Three bus write cycles are necessary to issue the Double Word Program command:
Read operations output the Status Register content after the programming has started.
Programming aborts if Reset goes to V
program operation is aborted, the block containing the memory location must be erased and
reprogrammed.
See
flowchart for using the Double Word Program command.
