Yes, the 8051 microcontroller has 128 bytes of RAM.

FURTHER, they're divided into three parts.

1. Register bank (32 bytes).
2. Bit addressable memory (16 bytes).
3.Read/ write storage/scratchpad (80 bytes).

The internal RAM memory of the standard 8051 microcontroller is 128 bytes. This internal RAM is used for data storage during program execution and is directly accessible by the CPU.

Details about the 8051 internal RAM:
It consists of 128 bytes of on-chip RAM at addresses 00H to 7FH.
The memory is divided into areas such as register banks, bit-addressable memory, and general-purpose RAM.
This RAM is volatile, used for temporary storage, and loses data when power is off.
The 8051 architecture also supports external RAM accessed via special instructions for larger data needs.
