Description
The 4116 is a new generation MOS dynamic random access memory circuit organized as 16,384 words by, 1 bit. As a state-of-the-art MOS memory device, the 4116 (16K advanced circuit techniques are designed to provide wide operating margins, both internally and to the system in speed and power previously seen only in MOSTEK’s high-performance MK 4027 (4K RAM).
This process, coupled with the use of a single transistor dynamic storage cell, provides the maximum possible circuit density and reliability while maintaining high-performance double-poly, N-channel silicon gate capability. out, including sense amplifiers, assures that power The use of dynamic circuitry through dissipation is minimized without any sacrifice in speed or operating margin. These factors combine to make the 4116 a truly superior
