TOSHIBA MOS MEMORY PRODUCT
32,76B WORD X B BIT N-MOS UV ERASABLE AND
ELECTRICALLY PROGRAMMABLE READ ONLY MEMORY

SILICON STACKED GATE MOS
TMM27256AD-20, TMM27256AD-200
DESCRIPTION
The TMM2 7256AD is a 32,768 word x 8 bit
ultraviolet light erasable and electrically program-
mable read only memory,
For read operation, the TMM27256AD's access
time is 150ns/200ns, and the TMM27256AD oper-
ates from a single 5-volt power supply and has low
power standby mode which reduces the power dis-
sipation without increasing a'ccess time, The standby
mode is achieved by applying a TIL-high level signal
to the CE input.
For program operation, the programming is
achieved by using the high speed programming
mode.
The TMM27256AD is fabricated with the N-chan-
nel silicon double layer gate MaS technology,
