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. RS Components offers a range of SDRAM products that vary in memory size from 16Mbit to 2Gbit.

What is the difference between RAM, DRAM, and SDRAM?

RAM or, Random Access Memory, is in almost all computing-capable devices, including 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. 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 in 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.

DRAM, or Dynamic Random Access Memory, is a type of RAM used for short-term data storage and uses one transistor to store data on one capacitor, but the data is lost once the capacitor loses its charge unless it is periodically recharged. This recharging is where the 'dynamic' is taken from. DRAM sends instructions to the processor as soon as it receives them, in contrast to SDRAM, or Synchronous Dynamic Random Access Memory, which is synchronised to the computer's clock. The difference this creates is that instructions join a pipeline of instructions to be processed, allowing for more commands to be received rather than waiting for one process to finish before allowing another to be received. This allows SDRAM to operate at much higher speeds than other forms of RAM.
