8051 internal ROM
ROM: Read Only Memory
is generally used to store data that does not change frequently, such as programs and tables.

Common ROM types:
Masked ROM (Masked ROM)
EPROM (Electrically Programmable ROM)
EEPROM (E2PROM)
Flash ROM
OTP ROM (One Time Programmable ROM)
The ROM of the 8051 microcontroller is a masked ROM:
Capacity: 4096byte (212)
Address range: 0000H～1FFFH
8051 internal RAM
RAM: Random Access Memory (random access memory)
is generally used to store a large amount of temporary data generated during program execution, which is equivalent to the memory of a PC.
