Title: Hitoshi Shimono: Innovator in Nonvolatile Memory Technology
Introduction
Hitoshi Shimono is a prominent inventor based in Kanagawa-ken, Japan. He has made significant contributions to the field of nonvolatile memory technology, holding a total of 3 patents. His work focuses on enhancing the efficiency and reliability of storage devices.
Latest Patents
One of Hitoshi Shimono's latest patents is a storage device that features a nonvolatile memory configured with blocks as deletion units. Each block contains several pages that serve as write units. The controller for this nonvolatile memory includes an error-correcting circuit that detects and corrects errors in data read from a page in one of the blocks. The controller also identifies when an error occurs that cannot be corrected. An error block table is utilized to store the logical address where the error occurred, along with a corresponding physical address.
Another notable patent is for a storage device and control method of nonvolatile memory. This invention includes a nonvolatile memory comprising physical sectors, each containing memory cells connected to a word line. Each memory cell can store data of at least 2 bits, and the physical sectors include pages corresponding to the number of bits storable in the memory cell. The controller is designed to receive a first write command and write data associated with that command to the nonvolatile memory. During the write process, the controller is configured to skip an upper page of a physical sector if its lower page is accessed by a second write command prior to the first.
