Embodiment Construction
[0029] The invention proposes a method for selecting an error correction circuit in a memory, mainly by dividing the data content in the memory into several parts, and using different error correction circuits for different parts to correct errors, so as to optimize the power consumption of the memory and appropriately reduce The size of the effective error correction circuitry in memory.
[0030] The method of the present invention mainly includes: step S1: providing a memory containing a plurality of error correction circuits with different performances; step S2: dividing the stored content in the memory into several grades according to the importance; All error correction circuits and levels are paired in such a way that higher error correction circuits protect more important content.
[0031] A method for selecting an error correction circuit in a memory proposed by the present invention will be described in detail below in conjunction with the accompanying drawings and sp...
