Abstract:
1. A sense amplifier for sensing and amplifying a current difference sensed from a memory cell of a memory array having multiple of even columns and multiple of odd columns, the sense amplifier comprising: a signal amplifying circuit for amplifying the current difference between a first signal line and a second signal line, the memory cell being located at a column of one of the multiple of even columns and the multiple of odd columns, the signal amplifying circuit being configured to produce a first amplified signal and a second amplified signal; and an output selecting circuit for selecting one of the first amplified signal and the second amplified signal, the first amplified signal being selected when the memory cell being sensed is located at one of the pair of odd columns, the second amplified signal being selected when the memory cell being sensed is located at one of the pair of even columns.
