Semiconductor memory having staggered sense amplifiers associated with a local column decoder

摘要

The invention relates to a semiconductor memory, comprising:
- bit lines,
- a memory cell array and,
- at least one pair of sense amplifier banks, wherein each sense amplifier is connected to a corresponding bit line according to an interleaved arrangement resulting in interconnect spaces available in each sense amplifier bank of the pair parallel to the bit lines,
characterized in that each sense amplifier bank further comprises at least one local column decoder for selecting at least one sense amplifier of the sense amplifier bank, the local column decoder being coupled to the at least one sense amplifier of the sense amplifier bank by means of an output line running in an available interconnect space parallel to the bit lines.
