A translation lookaside buffer (TLB) is a memory cache that stores the recent translations of virtual memory to physical memory. It is used to reduce the time taken to access a user memory location. It can be called an address-translation cache. It is a part of the chip's memory-management unit (MMU). A TLB may … See more A TLB has a fixed number of slots containing page-table entries and segment-table entries; page-table entries map virtual addresses to physical addresses and intermediate-table addresses, while segment-table … See more The CPU has to access main memory for an instruction-cache miss, data-cache miss, or TLB miss.
