RAM Memory Organization and Its Types of Memory

Memory is an important component of microcontrollers or CPUs for storing information that is used to controlelectronics projects. Internally, memory has been divided into several parts that consists of special types of registers those help to store data. There are two types of memories such as RAM memory and ROM memory, in many two are available in similar way. Here we will discuss about RAM memory organization of 8051 and its registers. This information is helpful for the embedded system designers to write program easily.

RAM Memory Organization of 8051 Microcontroller:

8051 microcontroller has 256 bytes of RAM memory, which is divided in two ways, such as 128 bytes for special function registers (SFR) and 128 bytes for general purpose memory. RAM memory organization contains a group ofgeneral purpose registers which are used to store information with a fixed memory address register, and SFR memory contains all peripheral related registers like ‘B’ register, Accumulator, Counters or Timers and interrupt related registers.
