Abstract:
1. A method of storing a data value in a volatile memory device having at least one memory cell, a word line and a pair of bit lines being coupled to the at least one memory cell, the method comprising: driving the pair of bit lines to complementary voltage levels representative of a data value to be stored; driving the word line to a voltage level to select the at least one memory cell and to thereby cause the at least one memory cell to be in a logic state representative of the data value to be stored; driving the word line to a voltage level to deselect the at least one memory cell; following the step of driving the word line to a voltage level to deselect the at least one memory cell, discharging the pair of bit lines to a voltage representative of a logic low level; and during the step of discharging the pair of bit lines, allowing a leakage current to flow through at least one of the bit lines so that the memory cell maintains the data value stored therein.
