Consequences of Port Restrictions on Testing Address Decoder Faults in Two-Port Memories
نویسندگان
چکیده
Testing two-port memories requires the use of single-port tests as well as special two-port tests; the test strategy determines which tests have to be used. Many two-port memories have ports which are read-only or write-only; this impacts the possible tests for single-port and two-port memories, as well as the test strategy. This paper discusses the consequences of the port restrictions (read-only or write-only ports) on the tests; in addition it covers the test strategy for address de-coder faults in two-port memories.

Testing Address Decoder Faults in Two-Port Memories: Fault Models, Tests, Consequences of Port Restrictions, and Test Strategy
A two-port memory contains two duplicated sets of address decoders, which operate independently. Testing such memories requires the use of single-port tests as well as special two-port tests; the test strategy determines which tests have to be used. Many two-port memories have ports which are read-only or write-only; this impacts the possible tests for single-port and two-port memories, as well...
متن کاملTest and Diagnosis of Word-Oriented Multiport Memories
Conventionally, the test of multiport memories is considered difficult because of the complex behavior of the faulty memories and the large number of inter-port faults. This paper presents an efficient approach for testing and diagnosing multiport RAMs. Our approach takes advantage of the higher access bandwidth due to the increased number of read/write ports, which also provides higher observa...
متن کاملAddress Decoder Faults and their Tests for Two-Port Memories
A two-port memory contains two duplicated sets of address decoders which operate independently. In this paper the effects of interference and shorts between the address decoders of the two ports on the fault modeling are investigated. Fault models and their tests are introduced, together with the test strategy.

متن کاملNew March Tests for Multiport RAM Devices
This paper describes three new march tests for multiport memories. A read (or write) port in such a memory consists of an n-bit address register, an n-to-2n-bit decoder (with column multiplexers for the column addresses) and drivers, and a K -bit data register. This approach gives comprehensive fault coverage for both array and multiport decoder coupling faults. It lends itself to a useful BIST...
