Word/Byte Configuration

Program and Erase Operation Status

During an erase or program operation, the system may check

the status of the operation by reading the status bits on I/O⁷-

I/O⁰. Standard read cycle timings and ICC read specifications

apply. Refer to "Write Operation Status" for more information,

and to each AC Characteristics section for timing diagrams.

Standby Mode

When the system is not reading or writing to the device, it can

place the device in the standby mode. In this mode, current

consumption is greatly reduced, and the outputs are placed in

an input for the LSB(A-1) address function.

during read operation. The internal state machine is set for

reading array data upon device power-up, or after a hardware

reset. This ensures that no spurious alteration of the memory

content occurs during the power transition. No command is

necessary in this mode to obtain array data. Standard

microprocessor read cycles that assert valid addresses on the

device address inputs produce valid data on the device data

outputs. The device remains enabled for read access until the

command register contents are altered.

If the device is deselected during erasure or programming,

the device draws active current until the operation is

completed.
