The type of memory integrated directly into the CPU chip for fast access to data is called cache memory. Cache memory is designed to store frequently accessed data and instructions, allowing the CPU to retrieve them more quickly than if it had to access data from the main RAM. It typically consists of multiple levels (L1, L2, and sometimes L3), with L1 being the fastest and located closest to the CPU cores. This speeds up processing and enhances overall system performance.
RAM (Random Access Memory) and SRAM (Static Random Access Memory) are the most commonly used types of memory used to hold instructions. RAM is the familiar chips you see people use to upgrade memory on the machine. SRAM is normally integrated and very expensive but much faster than normal RAM because it communicates directly with the processor.

Computer memory is a form of computer data storage, which takes the form of integrated circuits. There are two types of computer memory: Random-access memory (RAM) and Read-only memory (ROM).

RAM stands for Random Access Memory. This is the memory that a computer stores temporarily on an integrated circuit which allows any portion of the memory to be accessed with out moving through previous portions. Any portion of the memory can be accessed in the same amount of time as any other portion of memory since no physical process is used to access this memory.
An integrated memory controller (IMC) is a hardware component built into a computer's CPU that manages and controls the flow of data between the processor and the system memory (RAM). By having the memory controller directly on the CPU chip, it reduces latency and improves performance compared to traditional designs where the memory controller was located on the motherboard. This integration also allows for better power efficiency and faster data access, contributing to overall system performance. Most modern processors, including those from Intel and AMD, utilize an IMC.
The 8086/8088 has 20 address lines. It can access 220, or 1MB, or 1,048,576 bytes of memory.
