Latest Patents

One of Choe’s latest patents, “Storage Device, Operating Method of Storage Device, and Storage System Where Failure Signal Is Generated Based on Logical Address Mismatch,” describes a storage device with non-volatile memory divided into zones. A controller receives write requests and stores preliminary data in a second memory when a request’s logical address does not match the zone’s write pointer. This approach addresses mismatches between requested write locations and sequential zone-writing positions.

Another patent, “Storage Device and Operating Method of Storage Device,” concerns a non-volatile memory device organized into erase units and a memory controller. When a host requests an open zone, the controller allocates the zone to one or more erase units and permits sequential writes. It also maps sequential logical addresses to sequential physical addresses. If the host requests partial invalidation, the controller marks the relevant data as invalid while maintaining the map table.
