ABSTRACT:
A memory system includes a first memory, a second memory, a determining unit, and an accessing unit. The capacity of the second memory is different from the capacity of the first memory. The first and the second memories are virtually partitioned into a first section and a second section. The determining unit determines to which of the first and the second sections an address corresponds, the address being associated with data to be transferred. The accessing unit is coupled to the determining unit and the first and second memories for transferring the data to or from the first memory and a first portion of the second memory when the determining unit determines that the address corresponds to the first section; and for transferring the data to or from a second portion of the second memory when the determining unit determines that the address corresponds to the second section.
