Abstract
An associative memory system for logical addressing of memory segments using paged memory. The physical address of a targeted data word can be generated in one machine cycle if the segment logical base address and page index of the targeted word resides in an associated set of CAMs and RAMs. If the targeted word's logical base address and page index is not in the set of associated CAMs and RAMs, this information can be acquired at the most optimum rate for enabling data access. This rate may require several clock cycles.
