Abstract
A fully associative translation lookaside buffer (TLB) using a content addressable memory (CAM) array to store virtual addresses and a static random access memory (SRAM) array to store corresponding physical addresses. The TLB incorporates a logic circuit that allows the SRAM to be accessed during both associative and non-associative modes by word lines that are strictly a function of corresponding match lines. Additionally, the logic circuit incorporated in the TLB does not introduce any additional delay in outputting the physical address from the SRAM during the associative mode.
