DEVICE OPERATION
The operating modes of the M27C1001 are listed
in the Operating Modes table. A single power sup-
ply is required in the read mode. All inputs are TTL
levels except for V
Signature.
Read Mode
The M27C1001 has two control functions, both of
which must be logically active in order to obtain
data at the outputs. Chip Enable (E) is the power
control and should be used for device selection.
Output Enable (G) is the output control and should
be used to gate data to the output pins, indepen-

Standby Mode
The M27C1001 has a standby mode which reduc-
es the supply current from 30mA to 100 A. The
M27C1001 is placed in the standby mode by ap-
plying a CMOS high signal to the E input. When in
the standby mode, the outputs are in a high imped-
ance state, independent of the G input.
