DM93L38
8-Bit Multiple Port Register
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 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. The
circuit uses TTL technology and is compatible with all TTL
families.
Features
I
Master/slave operation permitting simultaneous write/
read without race problems
I
Simultaneously read two bits and write one bit in any
one of eight bit positions
I
Readily expandable to allow for larger word sizes
