Abstract
As disclosed herein, an integrated circuit memory is provided which includes primary sense amplifiers coupled for access to a multiplicity of storage cells, second sense amplifiers, and pairs of input/output data lines (IODLs), each IODL pair being coupled to a primary sense amplifier, and each IODL pair carrying complementary signals representing a storage bit. The memory further includes pairs of bi-directional primary data lines (BPDLs), each BPDL pair being coupled to a second sense amplifier and each BPDL pair being adapted to carry other complementary signals representing a storage bit. Local buffers are adapted to transfer, in accordance with control input, the complementary signals carried by the IODLs to the BPDLs, and vice versa.
