A semiconductor storage device 1 includes: an input controller (3); and a content-addressable memory block (2) connected to the input controller (3). Each word circuit (4) of the content-addressable memory block (2) includes: a k-bit 1st-stage sub word (4a) connected to search line 1 (SL1) of the input controller (3); and an (n-k)-bit 2nd-stage sub word (4b) connected to search line 2 (SL2) of the input controller (3). The k-bit 1st-stage sub word (4a) and the (n-k)-bit 2nd-stage sub word (4b) are separated by a segmentation circuit (5). When the 1st-stage sub word outputs a match signal, the match result is stored in the segmentation circuit (5), and a plurality of local match circuits within the 2nd-stage sub word (4b) are operated. |
