Method for writing data into flash memory is disclosed. The method includes storing the frequently updated data and the not-aligned data collectively into some of the physical memory blocks of the flash memory. In other words, the method collectively writes those data into the same physical memory blocks of the flash memory as far as possible. By doing this, the invalid physical memory pages in the physical memory blocks can be generated collectively. As a result, the storage releasing efficiency of garbage collection can be greatly improved.

Method for writing data into flash memory

The present invention discloses a control method of a multi-channel hybrid density memory storage device for access a user data. The storage device includes a plurality of low density memories (LDM) and high density memories (HDM). The steps of the method comprises: first, determining where the user data transmitted; then, using one of two error correction circuits which have different error correction capability to encode or decode the user data.
