Solid state drive with hybrid storage mode

摘要

A solid state drive (SSD) with a hybrid storage mode includes a flash memory, and a data processing module in information communication with the flash memory. The flash memory includes a first storage sector that stores data by a first potential storage mode, and a second storage sector that stores data by a second potential storage mode. The first storage sector corresponds to physical block addresses P0 to PM−1 and logical block addresses L0 to LM−1. The second storage sector corresponds to physical block addresses PM to PM+N−1 and logical block addresses LM to LM+1−1. The data processing module has a data processing mode. In the data processing mode, the data processing module identifies the logical block address included in a command, and executes the command at the corresponding physical block address. Accordingly, an SSD having a high stability and a high data storage capacity is provided.

1. A solid state drive (SSD) with a hybrid storage mode, comprising:
a flash memory, comprising a first storage sector that stores data by a first potential storage mode and a second storage sector that stores data by a second potential storage mode different from the first potential storage mode, the first storage sector comprising M data blocks, the second storage sector comprising N data blocks, each of the data blocks corresponding to a physical block address and a logical block address, the first storage sector corresponding to physical block addresses P0 to PM−1 and logical block addresses L0 to LM−1, the second storage sector corresponding to physical block addresses PM to PM+N−1 and logical block addresses LM to LM+N−1; and a data processing module, being in information communication with the flash memory, having a data processing mode in which the data processing module receives a command, identifies the logical block address included in the command, and executes the command at the corresponding physical block address; wherein the data processing module further has a data modulation mode in which a potential modulation command is added to the command to change the original potential storage mode of the command.
