A translation look-aside buffer (TLB) capable of reducing power consumption and
improving performance of a memory is provided. The fully-associative TLB which
converts a virtual address into a physical address, comprises a first TLB having
a plurality of banks; a second TLB having a plurality of entries, each of which
having one virtual page number and 2N physical page numbers, wherein
N is a natural number; and a selection circuit for outputting an output signal
of the first TLB to the second TLB in response to a selection signal, wherein each
bank of the first TLB has a plurality of entries, each of which has one virtual
page number and one physical page number. The size of a page indicated by a virtual
page number of the first TLB is different from the size of a page indicated by
a virtual page number of the second TLB.
