pBIST read only memory image compression

摘要

A programmable Built In Self Test (pBIST) system used to test embedded memories where a plurality of memories requiring different testing conditions are incorporated in an SOC. The pBIST Read Only Memory storing the test setup data is organized to eliminate multiple instances of test setup data for similar embedded memories.

1. A System On Chip disposed on a single integrated circuit having an embedded memory test system comprising:
a plurality of embedded random access memories having a plurality of memory types; a read only memory storing instructions for testing each of the plurality of types of embedded random access memories and data for testing the embedded random access memories; and a programmable Built In Self Test (pBIST) engine coupled to each of the plurality of embedded random access memories and to the read only memory, the pBIST engine operable to test each of the plurality of embedded random access memories employing instructions stored in the read only memory corresponding to the memory type of the embedded random access memory and data stored in the read only memory.
