Abstract

A test circuit for memory having plural memory cells and address latches responsive to addressing circuitry for reading/writing to said memory cells in a normal mode, has first connecting circuitry for connecting the address latches to form a linear feedback shift register. The linear feedback shift register is responsive to a clock signal to provide a sequence of addresses for testing the memory in a test mode.
