Description
516K x 8 bit fast static random access memory
Manufacturer
Motorola
Datasheet
MOTOROLA
SEMICONDUCTOR TECHNICAL DATA
Advance Information
512K x 8 Bit Static Random
Access Memory
524,288 words of 8 bits. Static design eliminates the need for external clocks or
timing strobes.
allowing for greater system flexibility and eliminating bus contention problems.
Either input, when high, will force the outputs into high–impedance.
