MAPPING DESCRIPTORS FOR READ OPERATIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240296116 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 in the second cache include starting logical and physical addresses, as well as a quantity of addresses, to identify frequently accessed addresses.
- When a read command is received, the first cache is queried first, followed by the second cache if there is a cache miss, to determine the physical address of the data in the memory array based on the stored descriptors.
Potential Applications: - This technology can be applied in various memory devices to optimize read operations and improve access efficiency. - It can be used in computer systems, servers, and other devices where fast and efficient memory access is crucial.
Problems Solved: - Addresses the issue of slow read operations in memory devices by utilizing mapping descriptors to streamline the process. - Improves overall system performance by reducing access times and enhancing data retrieval speed.
Benefits: - Enhanced read operation efficiency and faster data access in memory devices. - Improved system performance and reduced latency in accessing data from the memory array.
Commercial Applications: - Optimizing memory access in servers, data centers, and high-performance computing systems. - Enhancing the performance of consumer electronics devices such as smartphones, tablets, and laptops.
Questions about Mapping Descriptors for Read Operations: 1. How does the use of mapping descriptors in memory devices improve read operation efficiency? 2. What are the potential drawbacks or limitations of relying on mapping descriptors for read operations?
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.
