MAPPING DESCRIPTORS FOR READ OPERATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18602994 titled 'MAPPING DESCRIPTORS FOR READ OPERATIONS

The patent application describes methods, systems, and devices for mapping descriptors for read operations in a memory device.

  • The memory device includes a first cache with a mapping table between logical and physical addresses, and a second cache with descriptors of physical addresses in the memory array.
  • Descriptors contain starting logical and physical addresses, and a quantity of addresses, identifying frequently accessed addresses or sets of addresses.
  • When a read command is received, the first cache is queried first, followed by the second cache if there is a cache miss.
  • The physical address of the data in the memory array is determined and accessed based on the descriptors stored in the second cache.
      1. Potential Applications:

Original Abstract Submitted

Methods, systems, and devices for mapping descriptors for read operations are described. A memory device may include a first cache may include a mapping table between the logical addresses and the physical addresses, and a second cache may include one or more descriptors of one or more physical addresses of the memory array. A descriptor may include a starting logical address, a starting physical address, and a quantity of addresses in the descriptor, and may be configured to identify addresses or sets of address that are frequently accessed. When an access command (e.g., a read command) is received, the first cache may be queried and then the second cache may be queried (if there is a cache miss at the first cache). The physical address of the data of the memory array may be determined (and accessed) based on the descriptors stored in the second cache.
