Bit line and word line
WebA 1-T DRAM cell consists of a single transistor connected in series with a capacitor. For a read, the bit line is precharged to VDD/2 by a clocked precharge circuit. Then, the access transistor is turned on by applying VDD to the word line. A write is performed by applying VDD or GND to the bit line and VDD to the word line. WebThe bit lines and unaddressed word lines are held at ground while the addressed word line is driven to V dr . During reading, all cells connected to the addressed word line are set to 1, the ...
