Second of the five elements, we will explain about the memory that is in charge of storage.
Memory has two operations: Memorizing, and reading storage data and instructions.
Normally, either the "Memorizing" or "Reading" operation is selected by the signal from the CPU.
In the case of a microcontroller, the "Memorizing" operation is said to "write" because the CPU instructs to the memory for "writing".
The "Reading" operation is said to "Read" because it reads from the memory.
Memory is categorized into a code area and a data area.
The code area is where it places the program.
The data area is where it places the data.
