General Description

The DM93L38 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 common 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. The circuit uses TTL technology and is compatible with all TTL families.

Features

■ Master/slave operation permitting simultaneous write/read without race problems

■ Simultaneously read two bits and write one bit in any one of eight bit positions

■ Readily expandable to allow for larger word sizes
