Title: Kazuhiko Sanada: Innovator in Non-Volatile Memory Technology

Introduction

Kazuhiko Sanada is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of non-volatile memory technology, holding a total of 10 patents. His innovative work has paved the way for advancements in data storage solutions.

Latest Patents

One of his latest patents is focused on a non-volatile memory with an erase verify skip feature. This non-volatile storage apparatus is designed to perform erase verification during the erase process to account for differences in erase speed. To reduce the time required for the erase process, which includes the erase verify, the operation is skipped for certain memory cells based on a system parameter. For instance, when erasing a block of memory cells, a series of erase voltage pulses are applied to the NAND strings in both outer and inner sub-blocks of the block. Erase verify is conducted between erase voltage pulses for NAND strings in the outer sub-blocks while skipping the verify for those in the inner sub-blocks. The process of performing erase verify for the inner sub-blocks begins after a predetermined number of erase voltage pulses have been applied to the outer sub-blocks.
