TOSHIBA MOS MEMORY PRODUCT
4,096 WORD X 4 BIT STATIC RAM
SILICON MONOLITHIC
N-CHANNEL SILICON GATE MOS PROCESS
TMM2068AO-25, TMM2068AO-35
TMM2068AO-45
DESCRIPTION
The TMM2068AD is a 16,384 bits high speed and low power static random access memory
organized as 4,096 words by 4 bits and operates from a single 5V supply.
Toshiba's high performance device technology provides both high speed and low power ,
features with a maximum access tin~ of 25ns/35ns/45ns and maximum operating current
(If 135/l20/120mA h'hen L5 goes'high, the device is deselected and placed in a ](l....'
po\,'er standby mode in \,'hich maximum standhy current is 2OrnA.
Thus the T~m2068AD is nost suitable for us in cache memory and high speed storage
The TN!-12068AD is offered in a 20 pin standard cerdip package ....'ith 0.3 inch width jor
high density assembly.
The T~~12068AD is fabricated with ion implanted N channel silicon gate MOS technology
f or high perf ornance and high reI iabiJ i ty.
