Charge sharing dram

WebThe charge (Q) stored in a capacitor is equal to capacitance times voltage (Q = C x V). Over the years, DRAM operating voltage has decreased (i.e., 12V to 5V to 3.3V). As voltage decreases, the stored charge will also decrease. Design improvements allow for the decrease in the cell charge as long as the capacitance remains in the range of 30fF. WebFeb 3, 2024 · We studied and characterized those behaviors with a customized DRAM controller and unmodified DRAM modules from multiple vendors. The first work, ComputeDRAM, proposes DRAM command sequences that can open multiple DRAM rows at the same time, thereby enabling bit-line charge sharing.

WebEnabling a DRAM row starts the charge sharing process. Each DRAM cell connected to the DRAM row starts sharing its charge with its bitline. This causes the bitline voltage to deviate from \( \frac{V_{DD}}{2} \) (i.e., the charge in the cell perturbs the bitline voltage).
