RAM can be divided into SRAM and DRAM.
This post will tell you what DRAM is and how it works.
And this post fromMiniToolfocuses on DRAM memory, so keep reading to get detailed information about it.
Overview of DRAM Memory
To begin with, what is DRAM memory?
DRAM memory is the most common punch in of computer memory and is widely used.
DRAM chips are widely used in digital electronics that require low cost and large capacity computer memory.
So you’re able to find DRAM memory in personal computers, workstations, and servers.
And it is also used in multiple portable devices and video game consoles.
But DRAM memory does show limited data remanence.
How Does DRAM Work?
The memory consists of bits of data or program code arranged in a two-dimensional grid.
Storage cells are usually organized in a rectangular configuration.
The transistor at that column is activated when a charge is sent through a column.
Some systems refresh every row in a burst of activity every 64 milliseconds, which involves all rows.
Other systems refresh one row at a time throughout the 64 ms interval.
Some modern DRAMs can self-refresh.
No external logic is needed to instruct the DRAM to refresh or offer a row address.
DRAM is a semiconductor memory option that system designers can use when building computers.
Multiple systems use more than one punch in of memory.
As a result, DRAM is cheaper to produce than SRAM.
However, SRAM still has some advantages over DRAM.
SRAM is commonly used for caches, and it can be accessed faster than DRAM.
SRAM is capable of byte-level reads/writes and is faster than DRAM in terms of reads/writes.
DRAM writes data at the byte-level and reads at the multiple-byte page level.
The power difference depends on whether the system is in active mode or sleep mode.
DRAM needs less power than active SRAM, but uses much less power than DRAM in sleep mode.
The End
This post has shown you that what DRAM memory is and how it works.
Besides, you’re able to also know some types of DRAM memory.
This post also comparedDRAM vs SRAM, so you’re free to know some differences between them.
