Latest Patents

One of Rintaro Arai's latest patents is a memory system that controls the timing of refresh operations. This innovative memory system includes a non-volatile memory with first and second memory cell units, along with a controller that connects to a host. The controller is designed to store execution times for write and erase operations related to the first memory cell unit. It receives power-on time information from the host, determines a first time period based on the last write or erase operation, and calculates the execution time for the refresh operation. This allows for the effective transfer of data from the first memory cell unit to the second memory cell unit at the appropriate time.

Another significant patent involves a storage device and reading method. In this embodiment, the storage device comprises a non-volatile memory and a controller. The controller reads data from the non-volatile memory by applying a read voltage. It is also configured to correct the read voltage based on the difference between a measured value of a bit number obtained during the reading process and the expected value of that bit number.
