Abstract
A method for giving program commands to a flash memory chip is provided, the method is suitable for writing data from a host system into the flash memory chip. In the present method, a plurality of host write commands and data corresponding to the host write commands are received from the host system by using a native command queuing (NCQ) protocol, and cache program commands are gived to the flash memory chip to write the data into the flash memory chip. Accordingly, the time for executing the host write commands is effectively shortened by writing the data through the cache program commands and the NCQ protocol.
