How often does a memory controller automatically refresh memory in dynamic RAM?
Thousands time per second.........
How many types of ram r there?
There are three main types. DRAM - Dynamic Ram, which is the RAM in most computers. It's called Dynamic because there is a need for circuitry in the computer to constantly refresh the data. It will lose all data if power is removed. SRAM - Static Ram. Not as common but used to be used in laptops and portable devices. Called Static as you don't have to refresh all the time, but it does lose the data if you turn the power off. It is lower power than DRAM, but not as high capacity Flash RAM - though there are lots of names for this. Used in USB keys etc. It saves data even after the power is turned off. Access to it is a lot slower than DRAM.
What refers to the process by which the computer rewrites data to RAM?
Refresh
Differentiate between static ram and dynamic ram in tabular form any two differences?
· Static RAM: No refreshing, 6 to 8 MOS transistors · Dynamic RAM: Refreshed periodically, 3 to 4 transistors. · Static ram is more reliable · Dynamic ram is less reliable · Static ram is more expensive · Dynamic ram is less expensive · Static ram can store its data when computer is turned off · Dynamic ram looses data when computer is turned off. · A static memory cell takes a lot more space on a Chip than a dynamic memory cellby syed9230088668199

How can you refresh the memory in 8085?
Refreshing memory is not an 8085 specific thing. It has to do with the hardware design of the dynamic RAM used in the system, so it is impossible to give an answer without details of the particular system. In general, however, "quick and dirty" memory refresh schemes use a recurring interrupt at some frequency, and the interrupt service routine scans through a list of row or column addresss in RAM to execute a manual refresh cycle. The very big downside of this scheme is that you can never stop the processor with the READY pin for more than a very, very short period of time without risking the loss of all of RAM. This complicates debuggers, though it does not make them impossible. As far as the 8085 itself, internal refresh occurs automatically, so long as you maintain a certain minimum clock speed, typically 500KHz.

What electronic devices are used to store data in Dynamic RAM?
Basically, a dog is commonly used as a device to store data into a Dynamic RAM
What are the salient features of dynamic RAM?
The dynamic memory is formed of MOSFET and capacitor only. Hence it it is less bulkier than static RAM.
Why is the dram called the dynamic RAM?
because the D in Dram is short for dynamic....
