The MK4564 is the new generation dynamic RAM. Organized 65,536 words by 1 bit, it is the successor to the industry standard MK4116. The MK4564 utilizes Mostek's Scaled POLY 5 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 t.
o Recognized industry standard 16-pin configuration from
Mostek
o Single +5V (± 10%) supply operation
o On chip substrate bias generator for optimum
performance
o Low power: 300 mW active, max
22 mW standby, max
o 150 ns access time, 260 ns cycle time (MK4564-15)
200 ns access time, 330 ns cycle time (MK4564-20)
o Extended DOUT hold using CAS control (Hidden Refresh)
o Common I/O capability using "early write"
o Read, Write, Read-Write, Read-Modify-Write and Page-
Mode capability
•
