Memory device access management using encoding and decoding
A recently granted patent (Publication Number: US11994985B2) discloses a method for access management of a memory device in a Host Performance Booster (HPB) architecture. The method involves encoding internal information of the memory device within the memory controller and sending it to a host device for storage as host-owned encoded device side table information. Multiple entries of an address mapping control table are generated and stored in the memory controller's random access memory (RAM) as device side table information. When a reading request is received from the host device, a decoding procedure is used to obtain partial information from the host-owned encoded device side table information, which is then checked for reliability to determine the physical address associated with the logical address. The method ensures secure and efficient access management of the memory device within the HPB architecture.
Furthermore, the patent also covers a memory device and an electronic device incorporating the disclosed method. The memory device comprises a non-volatile (NV) memory and a controller that encodes internal information, generates address mapping control table entries, and decodes information for access management. The electronic device includes the memory device, a host device, at least one processor, and a power supply circuit. The controller's encoding and decoding procedures, along with the address mapping control table entries, facilitate reliable and secure data access between the memory device and the host device. Overall, the patented method and devices offer an innovative approach to memory access management in HPB architecture, enhancing performance and data security in electronic systems.
