Abstract
A memory apparatus and a data access method thereof are provided. The memory apparatus includes a first memory unit and a second memory unit, wherein an access speed of the second memory unit is higher than an access speed of the first memory unit. The method includes: receiving write data and a corresponding write address; comparing the write data with data corresponding to the write address in the second memory unit, so as to determine whether to write the write data into a current physical memory page of the first memory unit and into the second memory unit; after a data writing operation is executed, executing a data arranging operation on the current physical memory page according to the data in the second memory unit when the current physical memory page is full; and when a read command is received, reading the corresponding data in the second memory unit.
