Abstract (en)

[origin: DE19903198C1] The semiconductor memory device has memory cells (MC) formed at the intersection points between word lines (WLi) and bit lines (BLi), with a differential read amplifier (SA) coupled to 3 of the bit lines via a multiplexer (MUX), allowing the difference inputs of the amplifier to be coupled to any 2 of the 3 bit lines. Complementary data can be stored in 2 memory cells coupled to the same word line, with the memory cell bit lines coupled to the difference inputs of the read amplifier via the multiplexer.
