Abstract:
Aspects of the invention provide for reducing BIST test time for a memory of an IC chip. In one embodiment, a BIST architecture for reducing BIST test time of a memory for an integrated circuit (IC) chip, the architecture comprising: a pair of latches for receiving bursts of data from a memory; a first compression stage for receiving a burst of data and compressing the burst of data into a plurality of latches; a second compression stage for comparing the compressed bursts of data with expected data; and a logic gate for determining whether there is a fail in the burst of data.
