CACHE MANAGEMENT IN A MEMORY SUBSYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18612870 titled 'CACHE MANAGEMENT IN A MEMORY SUBSYSTEM

Simplified Explanation

The patent application describes methods, systems, and devices for cache management in a memory subsystem. An interface controller with two buffers is used to operate volatile memory as a cache for non-volatile memory.

Key Features and Innovation

Interface controller with first and second buffers for cache management
Facilitates data transfer between volatile memory, non-volatile memory, and other devices
Uses second buffer to transfer data from volatile memory to non-volatile memory

Potential Applications

This technology can be applied in various systems where efficient cache management is required, such as in data storage devices, embedded systems, and high-performance computing.

Problems Solved

This technology addresses the need for effective cache management in memory subsystems, improving data transfer speeds and overall system performance.

Benefits

Faster data transfer between volatile and non-volatile memory
Enhanced system performance through efficient cache management
Improved overall reliability and stability of memory subsystems

Commercial Applications

Data storage devices
Embedded systems
High-performance computing systems

Questions about Cache Management

How does cache management improve system performance?

Cache management helps reduce data access times by storing frequently accessed data closer to the processor, improving overall system performance.

What are the key components of an interface controller for cache management?

An interface controller typically includes buffers, control logic, and data transfer mechanisms to facilitate efficient cache operations.

Original Abstract Submitted

Methods, systems, and devices for cache management in a memory subsystem are described. An interface controller may include a first buffer and a second buffer. The interface controller may use the first and second buffers to facilitate operating a volatile memory as a cache for a non-volatile memory. During an access operation, the interface controller may use the buffer to transfer data between the volatile memory, non-volatile memory, and another device. In response to the access operation, the interface controller may use the second buffer to transfer second data from the volatile memory to the non-volatile memory.
