Abstract: A memory array structure includes: a plurality of array sections and a plurality of mini-gaps, wherein each mini-gap is disposed between two array sections of the plurality of array sections. Each mini-gap includes: a local write device, for providing a data signal in response to a write enable signal and a write data signal, the data signal for performing a write operation on a memory cell of an array section; and a local sensor, for outputting a data signal in response to an activation command and a read enable signal. The memory array further includes a control logic for providing the write enable and read enable signals, and at least one main sense amplifier, for providing the write data signal to the local write device, receiving the data signal from the local sensor, and amplifying the received data signal for providing a read data signal to output data lines.
