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.
