    Abstract: The plurality of CAM cells MC are configured to discriminate a match or mismatch between stored data stored in advance and search data. A match line is coupled to a plurality of CAM cells, and has a voltage level controlled based on discrimination results of the plurality of CAM cells. A first transistor and a second transistor are coupled in series between a common match output line and a predetermined power source. The first transistor is controlled to be turned ON or OFF based on a voltage level of the match line, and the second transistor is controlled to be turned ON or OFF by a search enabling signal asserted at the time of a search operation.

    Abstract: A semiconductor device having an SRAM which includes: a monolithic first active region in which a first transistor and a fifth transistor are disposed; a second active region separated from the first active region, in which a second transistor is disposed; a monolithic third active region in which a third transistor and a sixth transistor are disposed; and a fourth active region separated from the third active region, in which a fourth transistor is disposed. Each driver transistor is divided into a first transistor and a second transistor (or a third transistor and a fourth transistor) and these driver transistors are disposed over different active regions.

    Abstract: A semiconductor integrated circuit which can respond to changes of the amount of retained data at the time of standby is provided. The semiconductor integrated circuit comprises a logic circuit (logic) and plural SRAM modules. The plural SRAM modules perform power control independently of the logic circuit, and an independent power control is performed among the plural SRAM modules. Specifically, one terminal and the other terminal of a potential control circuit of each SRAM module are coupled to a cell array and a local power line, respectively. The local power line of one SRAM module and the local power line of the other SRAM module share a shared local power line. A power switch of one SRAM module and a power switch of the other SRAM module are coupled in common to the shared local power line.

    Abstract: A semiconductor device includes a memory array having a plurality of associative memory cells arranged in a matrix form for storing entries. The memory array is divided into a plurality of memory blocks for sequentially performing a retrieval operation along a column direction, and further includes a plurality of match lines corresponding to the respective memory blocks and provided correspondingly to each memory cell row, a plurality of search lines corresponding to the respective memory blocks and provided correspondingly to each memory cell column, and a plurality of match amplifiers corresponding to the respective memory blocks and provided to the plurality of match lines. The match line provided correspondingly to the preceding memory block is set to become shorter than the match line provided correspondingly to the subsequent memory block. The memory array further includes a timing control unit for controlling timing for driving the search line of the subsequent memory block based on a length of the match line provided correspondingly to the preceding memory block.
