SDRAM

What is RAM?
RAM or, Random Access Memory, is in almost all computing-capable devices. Found in handheld devices like smartphones, tablets and games consoles as well as laptops, desktop computers, televisions and so much more. RAM enables these devices to process tasks, manage information and solve problems.

What are RAM Memory Chips?
Computer memory modules are typically in either DIMM or SO-DIMM formats made up of a PCB board with a range of small memory chips on board. An SDRAM memory chip is what enables the RAM module to process tasks required by the device it is installed in. The memory size of each chip on the module each contributes to the overall RAM size that is accessible by the device. Larger memory sizes typically allow for more tasks, greater problem-solving power or the ability to run more or larger pieces of software at any one time.

What is SDRAM?
SDRAM, unlike regular DRAM, operates while syncing with the CPU clock. This syncing means the RAM waits for the clock signal before it will respond to data input. Unlike regular DRAM that will respond immediately to input data, SDRAM has a pipelining function allowing the CPU to process multiple tasks in parallel.

Aside from memory size, access time and data rates are key to having the most efficient and high performing device possible. These two factors are what allow CPUs to access the system RAM and engage processes and solve problems. Shorter access times provide faster access, building more efficient working environments.

Data rates, measured in Megahertz (MHz), varies across types and sizes of RAM and combined with bus widths and access time, data rates play a large part of processing. The data rate is quite simply the speed at which data can be fed into and out of systems. This means time taken to feed a process into the RAM and then transfer the results of the process undertaken back to the computer or device using it. Higher MHz values on RAM provide faster transfer times allowing systems to both feed and receive information faster.
