What is RAM structure explain with block diagram?

What is RAM structure explain with block diagram?

A block diagram of a RAM unit is shown below: The n data input lines provide the information to be stored in memory, and the n data output lines supply the information coming out of particular word chosen among the 2k available inside the memory. The two control inputs specify the direction of transfer desired.

How does DRAM request a block of data?

With standard DRAM, the CPU requests data by sending the address of the row and the address of the column for every block of data that needs to be read to the memory controller. The memory controller then fetches the information from that memory location.

What is DRAM in VLSI?

Dynamic random-access memory (dynamic RAM or DRAM) is a type of random-access semiconductor memory that stores each bit of data in a memory cell consisting of a tiny capacitor and a transistor, both typically based on metal-oxide-semiconductor (MOS) technology.
