Latest Patents

Matsushita's latest patents include innovations in nonvolatile memory and nonvolatile memory apparatus. One of his notable inventions provides a technique that reduces the load on a controller by rapidly detecting n-bit errors during writing and erasing processes on a chip in error correction code (ECC) within nonvolatile memory. This flash memory includes multiple electrically erasable and writable nonvolatile memory cells, performing write-and-verify processing during write operations. It features an ECC determination circuit that counts the number of bits of write errors detected and outputs this information, along with a status register that holds pass/fail information of the write operation.

Another significant patent involves a device and signal processing circuit for magnetic recording. This magnetic recording/reproducing apparatus incorporates a partial-response equalization circuit that cuts off low-frequency signal components, including DC components. The maximum-likelihood decoder processes the reproduced signal outputted from the reproducing head, thereby reducing noise and distortion and minimizing the data detection error rate.
