Abstract: A semiconductor device includes: a memory circuit having a plurality of quadrants arranged at corners of the memory circuit and surrounding a bank control component; wherein a first quadrant of the plurality of quadrants includes a first bit cell core and a first set of input output circuits configured to access the first bit cell core, the first quadrant defined by a rectangular boundary that encloses portions of two perpendicular edges of the memory circuit; wherein a second quadrant of the plurality of quadrants includes a second bit cell core and a second set of input output circuits configured to access the second bit cell core, the second quadrant being adjacent the first quadrant, wherein a border between the first quadrant and the second quadrant defines a first axis about which the first quadrant and the second quadrant are symmetrical.

Abstract: A memory is provided with a pseudo-differential sense amplifier for single-endedly sensing a first read bit line from a first bank of bitcells. The sense amplifier compares a voltage of the first read bit line to a voltage of a pre-charged second read bit line from a second bank of bitcells to make a bit decision for a read operation through the first read bit line to the first bank of bitcells.
