Latest Patents

Ishikawa's recent patents include a "Semiconductor Memory Device Test Apparatus" and "Semiconductor Memory Test Equipment." The test apparatus allows a memory device under examination to be accessed via an address generated by a pattern generator. It facilitates the writing of data and reading it back for comparison with expected outcomes. Notably, if a mismatch occurs, the comparison result is stored in a fault-address memory, and any detected faults trigger a fault signal if they exceed a predetermined threshold.

In the "Semiconductor Memory Test Equipment," Ishikawa has designed a system that uses an address from a pattern generator to read out memory and compare the obtained data to expected values using a comparator. This innovative approach employs a block mask memory to inhibit the comparison operation for specific addresses, thereby enhancing the testing process.
