  • Publication number: 20080008017
    Abstract: In memory array of a memory circuit, a discharging module and an auxiliary module are disposed on each column line. While accessing an objective memory unit on a column line of the memory, the memory unit discharges the corresponding row line of the objective memory unit according to a discharging signal and a column selective signal. When the objective memory unit is enabled, the voltage level of the corresponding column line is changed, if the voltage level reaches a threshold voltage level, the auxiliary module enhances the increment of the voltage level of the column line.

  • Patent number: 7257041
    Abstract: In a memory circuit, memory cells are arranged in a matrix by “row line-and column line” (may also denoted as “word line and bit line”). The invention provides a memory circuit and related method capable for independently pre-charging the column lines or bit lines selectively during data accessing according to results of column pre-decoding to decrease the pre-charging power consumption. After pre-charging, the objective memory cell is enabled to change or not to change the corresponding electric level of the connected column line according to the stored data, and a sense amplifier detects the stored data by measuring the electric level of the column line.
