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.

<storage, architecture> (TLB) A table used in a {virtual
memory} system, that lists the physical address page
number associated with each virtual address page number.
A TLB is used in conjunction with a cache whose tags are
based on virtual addresses. The virtual address is presented
simultaneously to the TLB and to the cache so that cache
access and the virtual-to-physical address translation can
proceed in parallel (the translation is done "on the side").
If the requested address is not cached then the physical
address is used to locate the data in main memory. The
alternative would be to place the translation table between
the cache and main memory so that it will only be activated
once there was a cache miss.
