Abstract

The invention introduces a method and an apparatus for controlling different types of storage units, the apparatus at least including: an interface and a processing unit. The interface connects at least two types of storage units, which include at least a nonvolatile hybrid memory. The processing unit is coupled to the interface and configured to operably access data to the different types of storage units through the interface. The arrangement of the hybrid memory can provide more diverse application potentials for the master device, and the hardware cost can be saved by connecting the hybridmemory to the integrated interface.

Description

technical field [0001] The invention relates to a storage device, in particular to a method and device for controlling different types of storage units. Background technique [0002] Flash memory is usually divided into NOR flash memory and NAND flash memory. The NOR flash memory is a random access device, and the host device (Host) can provide any address for accessing the NOR flash memory on the address pin, and obtain the data stored at the address from the data pin of the NOR flash memory in time. In contrast, NAND flash memory is not random access, but sequential access. NAND flash memory cannot access any random address like NOR flash memory. Instead, the master device needs to write the value of the sequence of bytes (Bytes) into the NAND flash memory to define the type of the request command (Command) (for example, read , Write, Erase, etc.), and the address used on this command. The address can point to a page (the smallest data block for write operations in flas...
