What do you understand by DRAM and its refreshing?
Dynamic RAM (DRAM) is fundamentally the same as SRAM, but this retains data for only 2 or 4 ms on an internal capacitor. But after 2 or 4 ms, the contents of the DRAM should be fully rewritten (refreshed) since the capacitors that is store logic 1 or logic 0, lose their charges. The whole content of the memory is refreshed with 256 reads in a 2-to-4 ms interval. Also refreshing occurs throughout a write, a read or a particular refresh cycle.
Assembly Language Programming In this chapter we will discuss programming in assembly language and machine language. The difference in machine assembly and high
Q. Consider the circuit configuration shown in Figure. Let V i = 1V, R 1 = 1000, R 2 = 2000, and A = 3. (a) Compute i 2 . (b) If R 1 changed to 500 , recompute i 2 .
We commissioned a 'bad practice exemplar' by asking Plexus to modify a good design (provided by Valor) to demonstrate the most likely kinds of faults in each of the areas Design fo
