DESCRIPTION
The TC55417P/J is a 65,536 bit high speed static random access memory organized as
16,384 words by 4 bits using CMOS technology, and operated from a single 5-volt supply.
Toshiba's high performance device technology provides both high speed and low power
features with a maximum access time of 25ns/35ns/45ns and maximum operating current of
120mA/100mA/100mA at maximum cycle time. The TC55417P/J also features an automatic
stand-by mode. When deselected by Chip Enable (CE), the operating current is reduced
to 20mA. The TC55417P/J is suitable for use in cache memory and high speed storage,
where high speed/high density are required. The TC55417P/J is moulded in a 24 pin
standard plastic DIP and a 24 pin plastic SOJ, with 0.3 inch width for high density.
assembly. The TC55417P/J is fabricated with ion implanted CMOS silicon gate MOS tech-
nology for high performance and high reliability.
