! tUNITED TECHNOLOGIES MOSTEK MEMORY COMPONENTS 65,536 x 1-BIT DYN(AMIC RAM MK4564 P/N/J/E)-12 FEATURES o Recognized industry standard 16-pin configuration from Mostek o Single +6 V (± 1()oAI) supply operation o On chip substrate bias generator for optimum performance o Low power: 330 mW active, max 22 mW standby, max o 120 ns access time, 220 ns cycle time o Extended Dour hold using CAS control (Hidden Refresh) o Common 1/0 capability using "early write" o Read, Write, Read-Write, Read-Modify-Write and Page- Mode capability o All inputs TIL compatible, low capacitance, and protected against static charge o Scaled POLY 6™ technology o 128 refresh cycles (2 msec) Pin 9 is not needed for refresh DESCRIPTION The MK4664 is the new generation dynamic RAM. Organized 66,636 words by 1 bit, it is the successor to the industry standard MK4116. The MK4664 utilizes Mostek's Scaled Poly 6 process technology as well as advanced circuit techniques to provide wide operating margins, both internally and to the system user. The use of dynamic circuitry throughout, including the 612 sense amplifiers, assures that power dissipation is minimized without any sacrifice in speed or internal and external operating margins. Refresh characteristics have been chosen to maximize yield (low cost to user) while maintaining compatibility between dynamic RAM generations.
