Instruction RAM, also known as IRAM, is a type of memory used in microcontrollers and other embedded systems to store instructions that the processor will execute. IRAM is a high-speed memory that is typically located close to the processor, allowing for faster access and execution of instructions.
In microcontrollers, IRAM is often combined with data memory (known as Data RAM or DRAM) to form a single block of memory called Program Memory. This Program Memory is where the microcontroller stores the program code that it will execute.
IRAM is typically volatile memory, meaning that its contents are lost when power is turned off. To maintain the program code in IRAM, the microcontroller must be powered continuously. Some microcontrollers include a feature called EEPROM (Electrically Erasable Programmable Read-Only Memory) that allows the program code to be stored even when power is off.
IRAM is an essential component of microcontroller-based systems, as it allows for the fast and efficient execution of program code. Without IRAM, the processor would have to access program code from slower memory sources, which would result in slower overall performance.
