Abstract
A command transmitting method, a memory control circuit unit and a memory storage device are provided. The method includes: transmitting a plurality of command sequences and a state read command sequence to a memory interface coupled to a rewritable non-volatile memory module; and storing the plurality of command sequences by the memory interface, and transmitting the state read command sequence to the rewritable non-volatile memory module.
Claims12
A command transmitting method for a rewritable non-volatile memory module, the method comprising:
- transmitting, by a memory management circuit, a plurality of command sequences and a state read command sequence to a memory interface coupled to the rewritable non-volatile memory module, wherein the plurality of command sequences include a first command sequence and a second command sequence;
- storing the plurality of command sequences by the memory interface, and transmitting the state read command sequence to the rewritable non-volatile memory module,
- receiving, by the memory interface, a response signal returned by the rewritable non-volatile memory module for responding to the state read command sequence without transmitting the response signal to the memory management circuit;
- and
- selecting, by the memory interface, the first command sequence from the plurality of command sequences stored in the memory interface according to the response signal, and transmitting the first command sequence to the rewritable non-volatile memory module.
