The MK4BZ02/12 is a 16,384-bit, Non-Volatile Static RAM, organized 2K x 8 using CMOS and an integral Lithium energy source. The ZEROPOWERTM RAM has the characteristics of a CMOS static RAM, with the important added benefit of data being retained in the absence of power. Data retention current is so small that a miniature Lithium cell contained within the package provides an energy source to preserve data. Low current drain has been attained by the use of a full CMOS memory cell, novel analog support circuitry, and carefully controlled junction leakage by an all implanted CMOS process. Safeguards against in- advertent data loss have been incorporated to main- tain data integrity in the uncertain operating environment associated with power-up and power- down transients. The ZEROPOWER RAM can replace existing 2K x 8 static RAM, directly conforming to the popular Byte wide 24-pin DIP package (JEDEC). MK48Z02/12 also matches the pinning of 2716 EPROM and 2KX 8 EEPROM. Like other static RAMs, there is no limit to the number write cycles that can be performed. Since the access lime, read cycle, and write cycle are less than 250ns and require only + 5 volts, no additional support circuitry is needed for interface to a microprocessor.
