How computer RAM works?

A microprocessor, a memory chip similar to an integrated circuit (IC), for millions of transistors and capacitors are included. The most common form of computer memory, dynamic random access memory (draft), one transistor and one capacitor in a memory cell, which represent data have made one bit. Capacitor bit of information - one is 0 or 1. Transistor is a switch in the control circuit allows the memory chip that serves as a capacitor to read or change its state.

RAM random access memory means. This means that information can be taken in any order and stored on your computer. Ram your computer makes a temporary location process electronic data. This means that the RAM chips to continue to store information while the computer is the power of electricity. In other words, when the computer is shut down, all data is stored in RAM is lost. All actual computing CPU (Central Processing Unit) begins with.

Support and drivers Chipset CPU that controls how information between the CPU and other components of the PC include travel.

Memory and memory controller is part of the chipset and the CPU is established between the information flow.

A bus is a data path consisting of parallel wires and the CPU, memory and connects to other devices. Just how much and how fast data structure determines the motherboard can go around.

Memory bus with memory controller runs on a computer memory sockets. A new system frontside bus (FSB CPU), main memory, L2 cache and a bus controller (PAB) is behind.

CPU to memory controller sends a request to the memory and information is available when the report is received. The cycle length according to memory speed as well as other factors such as bus speed can change. Living on the Motherboard, system clock sends a signal to all components, like a metronome. Each click represents a clock is a clock cycle. A 100 million-per-second clock running at 100Mhz clock cycle represents. Every action is required at various functions clock cycle of clock time by a different number.

Many people believe that the processor speed is the speed of computers. Most of the time and other components of the system bus speed runs separately. Because written notice or processed by all CPU memory read, a system's performance dramatically affected by how fast information can travel between the CPU and memory. Therefore, the fastest memory technology significantly contributes overall system performance.

A cache is a relatively small amount (normally less than 1MB) of high speed memory and lives very close to the CPU. The most frequently requested data is designed to provide with the CPU. It takes a fraction of the time, compared with normal memory, the cache access.

Assumption that 20% of the time, what is needed is in cache. Tracks the reference memory cache, keep instructions most often used in top of the list. Once the cache is full, is less than required.

Today, most cache memory is included in CPU. It can be located outside the CPU. The CPU cache is called the closest level 1, near the liver, 2 etc.

Is a process in which two or more CPU Interleaving memory banks is among the alternates. Each time a CPU memory bank address, bank on one clock cycle needs to be restarted. CPU than other banks, while the first bank is resetting can save processing time
