Latest Patents

One of his latest patents is a semiconductor memory device and its test method. This invention involves a test circuit connected to a memory core integrated unit of SRAM. When the memory core integrated unit is to be tested, a test start signal is set to a high level. This allows one of a bit line and an inverted bit line to be used for data writing, while the test circuit sets data to the selected bit line. The other bit line is utilized for data reading, and the written data is set to this bit line during normal operation. The method determines whether each memory core is defective by confirming that the data set to the bit line and the data set to the inverted bit line are mutually inverted. This innovative test method enables the quick detection of defects in each memory core of semiconductor memory, such as SRAM.
