  • Patent number: 9159400
    Abstract: A semiconductor memory having bit lines and wordlines crossing each other, a memory cell array formed by memory cells arranged in rows and columns on crossover points of the bit lines and wordlines, and sense amplifier banks arranged on opposite sides of the memory cell array. Each sense amplifier bank has staggered sense amplifiers connected to a bit line according to an interleaved arrangement whereby bit lines alternate in the direction of the wordlines between bit lines coupled to different sense amplifiers. This results in interconnect spaces parallel to the bit lines. Also, each sense amplifier bank includes a local column decoder for selecting a sense amplifier and which is staggered with the sense amplifiers and coupled to the sense amplifier by an output line running in an available interconnect space parallel to the bit lines.
