q Reset command

The reset command provides a means of stopping execution of

the erase or program command safely. If the user inputs command

code FF16 in the second cycle after inputting the erase or program

command in the first cycle and again input command code FF16 in

the third cycle, the erase or program command is disabled (i.e.,

reset), and the M38B79FF is placed in the read mode. If the reset

command is executed, the contents of the memory does not

change.

q Device identification code command

By inputting command code 9016 in the first cycle, the user can

read out the device identification code. The command code is

latched into the internal command latch at the rising edge of the

___

WE input. At this time, the user can read out manufacture’s code

1C16 (i.e., MITSUBISHI) by inputting 000016 to the address input

pins in the second cycle; the user can read out device code D016

(i. e., 1M-bit flash memory) by inputting 000116.

These command and data codes are input/output at the same tim-

ing as for read.
