Nonvolatile memory NVM page frame initialization method, apparatus and system

Abstract

A method, device and system for initializing a page frame of an NVM.The method for initializing a page frame of an NVM comprises: determining whether partial initialization processing is required to be conducted on data in a page frame of an NVM (101); and if so, conducting initialization processing on data in partial positions in the page frame using a preset processing policy (102). When initialization is conducted on a page frame of an NVM, whether partial initialization processing is required to be conducted on data in the page frame of the NVM can be determined first, and if so, initialization processing can be conducted on data in partial positions in the page frame using a preset processing policy rather than the situation that initialization processing is conducted on data in all positions in the page frame in the prior art, thereby reducing the number of write operations conducted on the NVM as far as possible, and then increasing the system performance, prolonging the service life of a memory and reducing the energy consumption of write operations.

Description

technical field [0001] Embodiments of the present invention relate to storage technologies, and in particular to a non-volatile memory (Non-Volatile Memory, hereinafter referred to as: NVM) page frame initialization method, device and system. Background technique [0002] In a computer system, memory generally consists of a dynamic random access memory (Dynamic Random Access Memory, hereinafter referred to as DRAM). [0003] Due to the low integration level of the DRAM, the capacity is limited; moreover, the DRAM needs to be continuously refreshed to ensure that data is not lost, so the energy consumption is relatively high. Compared with DRAM, NVM consumes less energy and can achieve greater capacity due to its high integration. Therefore, as applications require more and more memory capacity and energy consumption, computer systems using NVM as memory are an important direction for future development. [0004] However, in a computer system using NVM as a memory, when ini...
