<h1>microcontrollers RAM is too little ? We will Explain why</h1>

There are several microcontrollers RAM  out there,some with quite a heap of RAM,all things considered.

For example,if I am going on mouser right away,I will see a range of microcontrollers accessible,and in terms of RAM they vary from this:[1]

This is an 8bit PIC10 with sixteen Bytes of information RAM.

All the way down to this:

Which is a 32bit MCU that includes a fully-featured ARM cortex M3 core in conjunction with a reasonably huge 6MB of RAM.
<h2><strong>Let’s be real here about microcontrollers RAM:</strong></h2>
none of those chips have memory capacities that even compare to fashionable PCs. however,you have got to think about wherever these chips can be used.



In a computer,you'll usually use DIMMs,which are memory sticks external to the mainframe. however,these are so much too space-inefficient for a few comes. Microcontrollers are utilized in the embedded area,wherever lower chip count suggests that lower board prices and smaller size: each thing which will be important depending on the project. These MCUs have their DRAM engineered directly on-chip,therefore there’s solely such a lot you'll cram on there.

Besides,as you may see,there’s an enormous quantity of selection within the MCU area. which suggests that one thing: varied demand. whereas a number of these microcontrollers end up getting used for terribly computationally-intensive stuff,plenty of them simply ought to do one straightforward job: as an example,several home appliances are controlled by an MCU. If all you would like is to close up your refrigerator’s cooling system once temps drop below a definite threshold,will it really make sense to use one thing like a Cortex M3? No. In fact,you’re likely to choose for something abundant nearer to it PIC10 MCU up above.

Space is the main reason why most microcontrollers RAM are too little . Because it can have up to six transistors per bit,SRAM takes up a lot of space. DRAM,on the other hand,only requires a single transistor and a capacitor.
