<p>The embodiment of the present invention discloses a method, apparatus and system for reading data, wherein the method implementation for reading data comprises the following steps: sending a first read command to a first flash memory chip, and when the response of the first read command is received, reading the data which the first read command points to; after sending the first read command to the first flash memory chip and before reading the data which the first read command points to, sending a second read command to a second flash memory chip; receiving the response of the second read command, and when the reading of the data which the first read command points to is completed, reading the data which the second read command points to. The embodiment above has the following positive effects: the second read command is sent after sending the first read command to the first flash memory chip and before reading the data which the first read command points to, through which the reading latency is multiplexed, thus there is no reading latency between readings of data. Therefore, the utilization rate of the I/O path is improved, and accordingly the reading speed is enhanced.</p> |
