Question

Which of the following devices requires an initialization process (a program) before it can be used? a) PROM b) EPROM c) SRAM d) SDRAM A device has a synchronous input. This means a) The input is used to initialize the device b) The input has two meanings depending on the device mode input c) The input determines the operational mode of the device d) The input will not be recognized until the devices sees a clock pulse e) (a) and (b) only You are building a modulo-n counter using 74LVC2G74 FFs. The decode logic should assert the clear inputs on the FFs when the counter output value is a) n b) n-1 c) 2^n d) 2^n-1

Explanation / Answer

17.The initialisation programming is required for the synchronous dynamic RAM controller.

The initialisation code is consists of one or more setup commands that will tell controller about the hardware interface to SDRAM and how fast the data can be refreshed. The initialisation code is usually written in assembly language and put in. Hardware initialisation module.
