Memory system comprising translation lookaside buffer and translation information buffer and related method of operation

摘要

A memory system comprises a translation lookaside buffer (TLB) configured to receive a virtual address and to search for a TLB entry matching the virtual address, and a translation information buffer (TIB) configured to be connected to the TLB and determine whether a physical address corresponding to the virtual address falls into a continuous mapping area if the TLB entry matching the virtual address is not found.

1. A memory management system, comprising:
a translation lookaside buffer (TLB) unit configured to receive a virtual address and search for a TLB entry matching the virtual address; and a translation information buffer (TIB) unit configured to receive a TLB miss signal from the TLB unit, wherein the TIB unit has at least one TIB entry comprising a virtual page start address, a virtual page end address, and physical address information, and the TIB unit determines whether a physical address corresponding to the virtual address falls into a continuous mapping area using physical address information obtained by accessing a memory and the virtual page end address, and wherein the TIB unit is configured to adjust a management size of the TLB unit according to the continuous mapping area, and the TLB unit allocates multiple different subsequent TLB entries according to a new management size obtained as a result of the adjustment.
