ID Read Mode
EPROM programmers to identify the device type automatically.
(1) Applying V
(2) Input command sequence
Standby Mode
(1) Control using CE and RESET
(2) Control using RESET only
Auto-Sleep Mode
device will automatically enter Sleep Mode and the current will be reduced to the standby current (I
However, if the device is in the process of performing simultaneous operation, the device will not enter Standby
Mode but will instead cause the operating current to flow. Because the output data is latched, data is output in
Sleep Mode. When the address is changed, Sleep Mode is automatically released, and data from the new address
is output.
Output Disable Mode
ID Read Mode is used to read the device maker code and device code. The mode is useful in that it allows
ID read can be executed in two ways, as follows:
There are two ways to put the device into Standby Mode.
This function suppresses power dissipation during reading. If the address input does not change for 150 ns, the

specified bank to ID Read Mode. Banks are specified by inputting the bank address (BK) in the third Bus
Write cycle of the Command cycle. To read an ID code, the bank address as well as the ID read address must
be specified. The maker code is output from address BK + 00; the device code is output from address BK + 01.
From other banks data are output from the memory cells. Inputting a Reset command releases ID Read

This method is used mainly by EPROM programmers. Applying V
