Latest Patents

Marumo's latest patents include a Nonvolatile Semiconductor Storage Device and a Read Voltage Correction Method. The first patent describes a memory that stores dummy data, which includes a first data area with more '0's than '1's and a second data area with more '1's than '0's. An ECC processor detects error bit numbers related to both data areas, and a calculator computes the relative difference between these numbers. A comparator then compares this difference with a predetermined value, allowing a corrector to adjust the read voltage based on the comparison results. His second patent outlines a memory control method that involves writing converted data into a memory, where the amount of '1's in the converted data is less than in the original data. This method also includes outputting reproduced data to a host system for processing.
