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