DRAM

DRAM stands for “dynamic random access memory.” This is a type of RAM (random access memory) which all computers have. DRAM is often used in PCs, laptops, smartphones, and tablets as well as many other types of computing devices. Simply put, it provides temporary storage for files that are used when the computer is running programs or applications.

Why DRAM is important?

   DRAM is essential because it allows your computer to run efficiently by providing quick access to essential data that your processor needs to operate at peak performance. Without DRAM, your processor would have to look through much slower storage mediums like hard drives or solid-state drives every time it needed data. That would slow down operations significantly.

Additionally, having enough RAM ensures that the programs you are running don’t bog down your system because they will remain cached in memory until they are no longer needed.

Does DRAM have any speed?

   Yes , The best DRAM can be decided using speed efficiency.DRAM speeds are measured in MHz (megahertz), with higher numbers indicating faster speeds. Generally speaking, the faster your RAM, the faster your computer will be able to read and write data from its main memory.

This means that, if you have faster RAM, you can access data more quickly and with fewer delays (i.e., latency). For example, if two computers have the same processor but one has twice as much DRAM operating at twice the speed of the other, then it will likely perform significantly better than its slower counterpart.

Types of RAM

DRAM memory is just one kind of RAM. And within the DRAM category, there are a few types to know.

1. SDRAM

Synchronous DRAM, or SDRAM, improves performance through its pins, which sync up with data connection between the main memory and the microprocessor. Computers have used this syncing feature since the mid-1990s.

2. DDR SDRAM

DDR SDRAM has the features of SDRAM but with twice the data transmission frequency. That’s why it’s called “double data rate SDRAM.”

3. ECC DRAM

This type of DRAM can find corrupted data and sometimes even fix it, thanks to its error-correcting code (ECC).

Does SIZE matters?

Yes ,DRAM comes in different sizes namely

• DIMM –A dual inline memory module (DIMM) is a small-scale circuit board that holds memory chips on the motherboard.
• RDIMM -A dual in-line memory module (DIMM) with improved Reliability. The RDIMM, which became available for DDR3 memory, uses a hardware register that buffers the control signals (not the application data) to the modules.
• UDIMM (unregistered memory) is a type of memory chip used mostly in desktop and laptop computers. More commonly called unbuffered memory, UDIMMs run faster than registered memory (RDIMM) and cost less, but are not quite as stable as RDIMMs
• SODIMM indicates a small outline DIMM (aka notebook form factor)
• LRDIMM is short for load-reduced dual inline memory modules. LRDIMM is a load-reduction (LR) DIMM (used in servers) that supports higher densities than RDIMMs and contains a memory buffer (MB) chip, as opposed to a register, in order to reduce and minimise the load on the server memory bus.
• ECC (which stands for Error Correction Code) RAM is very popular in servers or other systems with high-value data. It protects against data corruption by automatically detecting and correcting memory errors. Standard RAM uses banks of eight memory chips in which data is stored and provided to the CPU on demand.
