Abstract

A memory partitioning method is applied in a memory module having a plurality of physical blocks. The partitioning method includes the following steps. First, a partitioning command is received. Next, at least one first memory driving module and a second memory driving module are called according to the partitioning command. Then, at least one location code corresponding to one of the physical blocks is obtained according to the first memory driving module and/or the second memory driving module, and the physical blocks are divided into a first memory area and a second memory area according to the location code. Finally, the first memory driving module and the second memory driving module respectively partition the first memory area and the second memory area.

Claims

1. A memory partitioning method applied to a memory module having a plurality of physical blocks, comprising:

receiving a partitioning command;

calling at least one first memory driving module and a second memory driving module according to the partitioning command;

obtaining at least one location code corresponding to one of the physical blocks according to the first memory driving module and/or the second memory driving module, wherein the physical blocks are divided into a first memory area and a second memory area according to the location code; and

partitioning the first memory area via the first memory driving module and partitioning the second memory area via the second memory driving module.

2. The method according to claim 1, wherein the location code is obtained according to a first starting block parameter and a first block number parameter recorded in the first memory driving module.

3. The method according to claim 2, wherein when the first starting block parameter is set as zero, the location code is obtained according to the first block number parameter.

4. The method according to claim 1, wherein the location code is obtained according to a second starting block parameter and a second block number parameter recorded in the second memory driving module.

5. The method according to claim 4, wherein when the second starting block parameter is not zero, the location code is obtained according to the second starting block parameter.

6. The method according to claim 1, wherein the step of partitioning the first memory area and the second memory area comprises:

generating a first logic memory area corresponding to the first memory area via the first memory driving module;

generating a second logic memory area corresponding to the second memory area via the second memory driving module;

partitioning the first logic memory area into at least one first logic partition; and

partitioning the second logic memory area into at least one second logic partition.

7. The method according to claim 1, wherein the first memory area is driven by the first memory driving module, and the second memory area is driven by the second memory driving module.

8. The method according to claim 1, wherein the memory module is a flash memory or a non-volatile memory.
