9338/DM9338 8-Bit Multiple Port Register
General Description
The DM9338 is an 8-bit multiple port register designed for
high speed random access memory applications where the
ability to simultaneously read and write is desirable. A com-
mon use would be as a register bank in a three address
computer. Data can be written into any one of the eight bits
and read from any two of the eight bits simultaneously.
