Latest Patents

Kazushige Shimogama's latest patents include a memory testing device and a semiconductor memory test system. The memory testing device is designed to output various pieces of pattern data from a pattern generator in a desired order. It converts this data into a test pattern signal with a real waveform, which is then applied to each pin of a memory under test. The device features a pattern selector for each I/O pin, comprising multiple registers that store pattern selection control signals. This allows for precise selection of patterns through multiplexers controlled by the pattern generator.

The semiconductor memory test system facilitates failure analysis of memory devices by enabling the switching between two situations. One situation uses expected data for an address fail memory, while the other uses data that reflects the charge/discharge states in the memory cells. This system includes a prohibit means to prevent the output of an area inversion memory from transferring to later stages, along with an exclusive OR gate that processes the outputs to provide results to the address fail memory.
