ABSTRACT:
This invention comprises a pair of bit lines; a word line; a pair of data bus lines; bit line sense amplifying means connected to said pair of bit lines and said word line; a voltage difference to current difference converter connected to said bit line sense amplifying means through said pair of bit lines, for converting the voltage difference between said pair of bit lines to the current difference; current sensing means connected to said pair of data bus lines and a power source, for sensing a current flowing to said pair of data bus lines and holding a same voltage level in said pair of data bus lines; and current difference to voltage difference converting and amplifying means connected to said current sensing means, for converting the current difference occurred in said current sensing means to the voltage difference and amplifying the voltage difference.
