Suppose that a 2M x 16 main memory is built using 256K × 8 RAM chips and memory is word-addressable. a) How many RAM chips are necessary? b) If we were accessing one full word, how many chips would be involved? c) How many address bits are needed for each RAM chip? d) How many banks will this memory have? e) How many address bits are needed for all of memory? f) If high-order interleaving is used, where would address 14 (which is E in hex) be located?

:you areto design the controller for alight that functions both as an ordinary light and also as a motion activated light and alarm. a.if the manual switch s is on, then the light l is on. b.besides the manual switch, there is a motion detector, m1, which activatesthis light.c.if motion is detected but the light is on anyway because s is on, only then a secondoutput a, an alarm, is turned on. d.the disable switch, d, disables the motion activated light and alarmbut leaves manual control operation of the light using switch s.(i)read the problem statement and clearly identify the inputs and outputs for the circuit you are designing. (ii)create the truth table for this system; include the light, alarm, switch, disable, and the motion sensor.(iii)draw a schematic of this system.
