"WebApr 10, 2024 · PIT 7 UNIT 5 The sense amplifier specifies whether the cell contains a logic 1 or logic 2 by comparing the capacitor voltage to a reference value. The reading of the cell results in discharging of the capacitor, which must be restored to complete the operation. Even though a DRAM is basically an analog device and used to store the single bit (i.e., 0,1). " - Read write operation in dram

WebThe reason for this is the fact that the "data read" operation on the one-transistor DRAM cell is by necessity a "destructive readout." This means that the stored data must be destroyed or lost during the read operation. Typically, the read operation starts with precharging the column capacitance C. Web1. When reading the row then bits are amplified and sent back on the line as part of the feedback circuit. The bits are also stored in a small chunk of SRAM where they are cached …
