ABSTRACT:
A method and apparatus for fast memory access in a computer system employing a high-speed associative memory for storing extracts that each include an address and an associated information component. Each extract is associated with a presence indicator and a reference indicator, their respective states being changed when an extract is used. According to the method of the invention, the state of each reference indicator can be changed only if the number of extracts present is at least equal to a threshold value. The invention also relates to apparatus for implementing the method. The invention can be applied to cache memories and to translations of virtual addresses to real addresses.
