Title:
ASSOCIATIVE MEMORY RETRIEVAL CIRCUIT
Document Type and Number:
Japanese Patent JPH11185482
Kind Code:
A
Abstract:

To enable the update of retrieve addresses being generated by an increment type counter even if a value on the counter multiply coincides from the retrieve result.

A retrieve controller 1 initiates a count operation according to a retrieve request 101 and inputs a value thereof 107 to a CAM 4 as a select signal 101. The CAM 4 executing the retrieval in time and outputs a coincidence signal 103 and multiple coincidence signal 104 when data multiply coincide. Upon receipt of the coincidence signal 103 and multiple coincidence signal 104 the controller 1 outputs a hold signal 105. A retrieved result holder 5 holds an address output 111 as a retrieval output 112. A significant controller processes this address output 111 while the retrieve controller 1 outputs the previous retrieval data 107 as a retrieval hold data 108 which is then held by a retrieval holder 2, and executes the count of the retrieval data 107 again.
