    摘要: In a system for conducting virtual address translation in a virtual memory system and implementing a table such as a Translation Lookaside Buffer, a system and method enabling quicker access to tables entries in which the entries are addressed after adding a plurality of address parts wherein the plurality is two (2) or (3). Particularly, a smaller and/or faster adder is used having, for example, only n=2 ports in the time critical path. In order to make the exact address calculation, during array accesses, a multiplexor is implemented to decide, after the TLB arrays are accessed for preselection, which of a plurality of possible entries has to be taken.

    摘要: In a circuit that reduces power consumption in an array system of memory cells accessible in parallel, a local evaluation circuit is connected to a memory cell and a global bit line of the array system of memory cells. A selection circuitry splits the global bit line into an upper part and a lower part of the global bit line. The selection circuitry is adapted to receive an early set prediction signal and to connect the upper part of the global bit line to the lower part of the global bit line based on the early set prediction signal. The early set prediction signal indicates whether a set of memory cells, which include the memory cell, is being read. The circuit also includes a N:1 multiplexer connected to the lower part of the global bit line to receive the lower part of the global bit line as input.

    摘要: The present invention relates to content addressable memory (CAM), particularly, to a CAM having its memory array, which contains a plurality of memory locations, being divided into at least a first and a second memory block (100, 102), whereby the first and second memory block (100, 102) are formed by a first and second portion of each of said memory locations, respectively. The CAM further comprises a first set of compare lines (115) and a first set-of match lines (116) associated to said first memory block (100), and a second set of compare lines (117) and a second set of match lines (118) associated to said second memory block (102), and pre-charge units (112, 114) for charging said match lines before a comparison operation. The present invention provides an improved CAM which allows flagging of memory locations of which the content only partially matches a given comparison value. This is achieved by a CAM according to the above features using the pre-charge state of the match lines (116, 118) as a logically valid state.
