Patent ID: 8266334

Claim:
A data writing method, for writing data from a host system into a plurality of memory dies of a rewritable non-volatile memory storage apparatus, wherein a host interface of the rewritable non-volatile memory storage apparatus couples to a data transmission interface of the host system, the data writing method comprising: determining whether the data transmission interface of the host system complies with a first interface standard or a second interface standard according to information; using a general mode to write the data into the memory dies when the data transmission interface of the host system complies with the first interface standard, wherein the number of memory dies that are at a busy status or a transmission status at the same time among the memory dies is not larger than a first amount in the general mode; and using a power saving mode to write the data into the memory dies when the data transmission interface of the host system complies with the second interface standard, wherein the number of memory dies that are at the busy status or the transmission status at the same time among the memory dies is not larger than a second amount in the power saving mode.
