Can we upgrade on chip RAM of microcontroller?
If you need more storage space, you can add off-chip RAM or flash, or even send data to a remote PC. But for most MCU applications, extra capacity on the chip would go unused.
What is the order decided by a processor or the CPU of a controller to execute an instruction?
What is the order decided by a processor or the CPU of a controller to execute an instruction? Explanation: First instruction is fetched from Program Memory. After fetching, instruction is decoded to generate control signals to perform the intended task.
What is the purpose of RAM in microcontroller?
Microcontroller Systems Random access memory (RAM) is a general-purpose memory that usually stores the user data in a program. RAM is volatile in the sense that it cannot retain data in the absence of power; i.e., data is lost after the removal of power.

Why is RAM memory used in microcontrollers?
RAM memory in microcontrollers is usually lesser in size than flash memory. One of the reasons is discussed in the last section, the other important reason is that RAM memory has lower latency than flash memory.
How much memory does a 16 bit microcontroller have?
Most microcontrollers uses Harvard architecture, which has separate 16-bit address spaces for program memory, RAM, and memory-mapped I/O addresses. So for these, the 16-bit address bus can access up to 64K (65,536) bytes of RAM.
How can I increase the memory speed of my CPU?
If your CPU is not able to natively run Ballistix parts at their XMP profiles, then you might be able to achieve these speeds by overclocking your CPU bus. By overclocking the CPU to run at a faster speed, you naturally increase memory speed that the memory controller in the CPU can support.
Can a ram overclock increase the CPU temp?
RAM overclocking will increase the heat output of your CPU, but not by much if you’re just doing XMP. Manual overclocking will increase it a bit more, but if you’re running an adequate cooler to overclock your CPU, you should be good.
