How DRAM's are different from SRAM's? Why DRAMs are said to employ address multiplexing?
Dynamic RAM (DRAM) is fundamentally similar as SRAM, except that this retains data for only 2 or 4 ms on an internal capacitor. In this after 2 or 4 ms, the contents of the DRAM should be fully rewritten (refreshed) because the capacitors, that store logic 1 or logic 0, lose their charges. The whole content of the memory is refreshed along with 256 reads in a 2-to-4 ms interval. Refreshing also arises throughout a write, a read or throughout a special refresh cycle.
ELECTRICAL STARTER MOTOR This usually consists of a heavy duty, compound wound, DC motor, which draws its electrical supply from an external source. The motor works in conjunc
cite a specific example in which the engineer must provide maximum efficiency for a given cost.
Q. For a transistor, when v GS = -2.0 V, find V DSsat if Vp= -4.0 V for an n-channel depletion mode MOSFET. Solution: V p = -(V DSsat + v SG ) but v SG = -v GS = -(-
For the circuit of Figure(a), obtain the complete solution for the current i L (t) through the 5-H inductor and the voltage v x (t) across the 6- resistor.
The advantage of the analog storage oscilloscope is that it has higher bandwidth and writing speed than a digital oscilloscope, being capable of operating speeds of about 15 GHz. T
When both MT 2 and Gate are positive In this junction P 1 N 1 and P 2 N 2 are forward biased whereas junction N 1 P 2 is reverse biased. The gate current flows thr
