Abstract
Apparatus, systems, and methods to manage memory refresh operations are described. In one embodiment, an electronic device comprises a processor and memory controller logic to determine a memory refresh frequency for a memory system and transmit refresh commands to a refresh control logic in at least one memory bank coupled to the memory controller according to the memory refresh frequency. Other embodiments are also disclosed and claimed.
Claims25
An electronic device comprising:
- a processor;
- and
- a memory control logic to:
- determine a memory refresh frequency for a memory system;
- and
- transmit refresh commands to a refresh control logic in at least one memory bank coupled to the memory controller according to the memory refresh frequency.
3 more elements
A memory controller comprising logic to:
- determine a memory refresh frequency for a memory system;
- and
- transmit refresh commands to a refresh control logic in at least one memory bank coupled to the memory controller according to the memory refresh frequency.
An apparatus comprising:
- a memory device having a plurality of memory cells organized into rows;
- a memory register;
- and
- a memory refresh control logic to:
- determine a refresh requirement for one or more rows in the memory device;
- and
- store the refresh requirement in a memory register in association with a row address.
4 more elements
A method comprising:
- determining, in a memory controller, a memory refresh frequency for a memory system;
- and
- transmitting refresh commands to a refresh control logic in at least one memory bank coupled to the memory controller according to the memory refresh frequency.
