Abstract

The invention discloses a memory device, a data processing system and method, and a storage medium. A controller in a memory system is programmed to execute the following operations: an L2P management table is maintained; the L2P management table is configured to comprise a first-level management sub-table and a second-level management sub-table; the first-level management sub-table comprises a plurality of first elements; each first element corresponds to one second-level management sub-table; each first element is configured to contain first identification information; each second element contained in the secondary management sub-table is configured to contain second identification information; a physical area indicated by the second elements with second identification information of a second mark is obtained from a plurality of physical areas indicated by the first elements with first identification information of a first mark by using the L2P management table after responding to a request for an L2P pointer sent from a host device; and information associated with the first L2P pointer is stored using the physical area indicated by a certain second element of the second mark.

Description

technical field [0001] The present invention relates to the technical field of memory, in particular to a memory device, a data processing system, a method, and a storage medium. Background technique [0002] Memory systems are typically provided as internal semiconductor integrated circuits in computers or other electronic devices. There are many different types of memory, including volatile and nonvolatile memory. Volatile memory requires power to maintain its data and includes Random Access Memory (RAM, Random Access Memory), Dynamic Random Access Memory (DRAM, Dynamic Random Access Memory) or Synchronous Dynamic Random Access Memory (SDRAM, Synchronous Dynamic Random Access Memory) and so on. Non-volatile memory can retain stored data when it is not powered on, and includes Flash Memory (Flash Memory), Read Only Memory (ROM, Read Only Memory), Electrically Erasable Programmable ROM (EEPROM, Electrically Erasable Programmable Read- Only Memory), static RAM (SRAM, Stati...
