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.
From address BK + 00 the maker code is output; from address BK + 01 the device code is output. From other
banks, data are output from the memory cells. Inputting a Reset command releases ID Read mode and returns
the device to Read mode.

longer, the device automatically enters Sleep mode and the current becomes standby current (I
if the device is in simultaneous operation, the device does not enter Standby mode but causes the operating
current to flow. Because the output data are latched, data are output in Sleep mode. When the address is
changed, Sleep mode is automatically released, outputting data from the changed address.
Output Disable Mode
ID Read mode is used to read the device maker code and device code. The mode is useful for EPROM
In this method, simultaneous operation can be performed. Inputting an ID Read command sets the specified
Access time in ID Read mode is the same as that in Read mode. For the codes, see the ID Code Table.
There are two methods of entering Standby mode.
