Difference Between Sram & Dram

Reading and writing in RAM is easy and rapid and accomplished through electrical signals. Simple and uses capacitors and very few transistors. Single block of memory requires 6 transistors Only one transistor. Charge leakage property Not present Present hence require power refresh circuitry Power consumption Low High. Its construction is comprised of two cross-coupled inverters to store data binary similar to flip-flops and extra two transistors for access control. It consumes less power. SRAM can hold the data as long as power is supplied to it.

Difference Between SRAM & DRAM

RAM is a semiconductor device internal to the integrated chip that stores the processor that a microcontroller or other processor will use constantly to store variables used in operations while performing calculations. RAM refers to the hardware that provides the memory locations referred to in software as registers. As of this writing, all commonly used RAM is volatile, which means that everything in volatile memory is lost when power is removed. RAM is much faster to access than external memory and is a critical component to the speed of the processor chip. The architectural difference between the two is that DRAM uses transistors and capacitors in an array of repeating circuits where each circuit is one bit , whereas SRAM uses several transistors in a circuit to form one bit.

SRAM is called static as no change or action i. It is used in cache memories. Advantage: Low power consumption and faster access speeds. Disadvantage: Less memory capacities and high costs of manufacturing. Capacitors that store data in DRAM gradually discharge energy, no energy means the data has been lost. So, a periodic refresh of power is required in order to function. DRAM is called dynamic as constant change or action i.

Dynamic RAM is the most common type of memory in use today. Inside a dynamic RAM chip, each memory cell holds one bit of information and is made up of two parts: a transistor and a capacitor. These are, of course, extremely small transistors and capacitors so that millions of them can fit on a single memory chip. The capacitor holds the bit of information -- a 0 or a 1 see How Bits and Bytes Work for information on bits.
