Memory device, control method thereof and recording medium

A control method of a memory device may include: (a) reading a read request of a host; (b) determining, by the processor, whether a logical address corresponding to the read request of the host is present in a cache; and (c) generating, by the processor, a data read command according the read request when the determination result of (b) indicates that the logical address corresponding to the readrequest is present in the cache, and transferring, by the processor, the data read command to one of the plurality of memory channels which corresponds to the physical address, in order to process thedata read command. 本发明提供了一种存储器装置的控制方法。该控制方法可以包括：(a)读取主机的读取请求；(b)由处理器确定高速缓存中是否存在与主机的读取请求对应的逻辑地址；(c)当(b)的确定结果指示高速缓存中存在与读取请求对应的逻辑地址时，由处理器根据读取请求生成数据读取命令，并且由分别与多个存储器通道对应的存储器通道控制器中的一个或多个将数据读取命令传送至多个存储器通道中的与物理地址对应的一个，以便处理数据读取命令。该控制方法可以应用于具有存储器的装置，并且因此实施用于提高各种随机读取效率的方法。例如，该控制方法可以使用在存储器装置中优先处理数据读取命令的方法来提高由存储器装置执行的随机读取操作的效率。
