US 2026/0010467 A1 · MEMORY CAPACITY ADJUSTMENT METHOD AND APPARATUS, ELECTRONIC DEVICE, AND STORAGE MEDIUM

Abstract

A method and apparatus for adjusting a memory capacity, an electronic device, and a storage medium are provided by embodiments of the present application. The method includes: reading serial presence detect (SPD) data of a target memory from a basic input output system (BIOS) image of a BIOS, wherein the SPD data is reserved and the target memory is a physical memory without an SPD controller; and adjusting a memory capacity of the target memory based on the SPD data of the target memory. In the embodiments of the present application, dynamic adjustment on the memory capacity without SPD controllers may be achieved and dynamic adjustment on the memory capacity of an overall server without manually disassembling the memory modules of the server may be met, actual business needs of customers are met, the service life of memories is prolonged, and operation and maintenance costs are reduced.

Dependent claims

A method for adjusting a memory capacity, applied to a basic input output system (BIOS), the method comprising:

obtaining serial presence detect (SPD) data of a plurality of types of memories comprising the target memory;
building a data structural body corresponding to each memory parameter in an image of the BIOS;
storing SPD data of each type of the memories in a corresponding data structural body based on memory parameters of each type of the memories;
and
storing a data structural body of each type of the memories in a storage address corresponding to each type of the memories;
reading SPD data of a target memory from the image of the BIOS, wherein the SPD data of the target memory is reserved, and the target memory is a physical memory without an SPD controller;
and
adjusting a memory capacity of the target memory based on the SPD data of the target memory;
wherein the adjusting the memory capacity of the target memory based on the SPD data of the target memory comprises:
assigning the SPD data of the target memory to the target memory;
and
initializing the target memory to adjust the memory capacity of the target memory.
