Title: **Eugene Lisitsyn: Innovating Data Storage Solutions**

Introduction

Eugene Lisitsyn, an accomplished inventor based in Anaheim, California, has made significant contributions to the field of data storage technology. With a portfolio that boasts five patents, his work focuses on enhancing the functionality and reliability of data storage systems.

Latest Patents

Among Eugene's latest patents is a groundbreaking innovation centered on managing data for a data storage system. This technology involves receiving a host write command to incorporate host data connected with a logical address into a non-volatile memory. The process includes determining a first physical address linked to the logical address and checking whether that physical address is bad. If the address is found to be valid, it's marked as such, but if deemed bad, a valid count associated with a set of physical addresses is maintained while the bad address is marked invalid.

Another notable patent is related to preserving data upon a power shutdown. In this invention, host data segments are obtained and stored in a cached data unit, which is then linked to a previously stored data unit in non-volatile memory. Metadata is created to signify unmodified segments, including an update flag which indicates that updates are required. If a power interruption occurs unexpectedly, both the cached data unit and its associated metadata are securely recorded in a different memory area, ensuring data integrity is maintained. This innovation allows for seamless operation recovery after power restoration, enhancing the reliability of data storage solutions.
