Testing 256k word/spl times/16 bit Cache DRAM (CDRAM)

Abstract

Cache DRAM (CDRAM) is a promising high speed memory which can eliminate "memory bottleneck" in a computer system and can realize "unified memory" for a multi-media system. Test of a CDRAM is broken down to several sub-test steps. Testing a CDRAM comprises separated test and concurrent test of SRAM and DRAM. Dual PGs of ATE are powerful tools both for high speed and concurrent operation tests.
