Device description
Table 2
lists the operating modes of the M27C1001. A single power supply is required in
Read mode. All inputs are TTL levels except for V
PP
and 12V on A9 for Electronic Signature.

2.1
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, independent of device selection. Assuming that the addresses are stable,
the address access time (t
AVQV
) is equal to the delay from E to output (t
ELQV
). Data is
available at the output after a delay of t
GLQV
from the falling edge of G, assuming that E has
been low and the addresses have been stable for at least t
AVQV
-t
GLQV
.
2.2
Standby mode
The M27C1001 has a standby mode which reduces the supply current from 30mA to 100μA.
The M27C1001 is placed in the standby mode by applying a CMOS high signal to the E
input. When in the standby mode, the outputs are in a high impedance state, independent of
the G input.
2.3
Two-line output control
Because EPROMs are usually used in larger memory arrays, this product features a 2-line
control function which accommodates the use of multiple memory connection. The two line
control function allows:
the lowest possible memory power dissipation,
complete assurance that output bus contention will not occur.

For the most efficient use of these two control lines, E should be decoded and used as the
primary device selecting function, while G should be made a common connection to all
devices in the array and connected to the READ line from the system control bus. This
