Repair ram (INVENT BY AUTHOR)

##$ REPAIR R.A.M. $### (invented by me)

SOMETIMES OUR RAM GETS DESTROYED BY OVERHEATING OR ANY OTHER PROBLEM IT CAUSES DISPLAY PROBLEMS I SIMILARLY HAVE SAME ISSUE BUT I JUST THINK WHY I THROW THIS STICK I CAN GIVE IT ALAST CHANCE THEN I JUST DO FOLLOWING STEPS AND ITS NOW STARTED AND NOW I AM WRITING ON MY PC WITH THAT RAM WHICH REPAIRED EARLIER SO MY ONLY OPINION IS THAT WHENEVER YOU THROW YOUR RAM, PD, MEMS THEN ALWAYS GIVE THEM A LAST CHANCE SOMETIMES THEY CAN BE WORK BACK IT CAN ALSO SAVE SOME RUPPE/BUCK IN UR POCKET

SO TRY IT------

Hey friends if u have a ram that dont works den try this procedure 2 solve the problem

If ur ram is not working then do following simple steps:

Requirements: rubber, cleaning agent, not working ram, a brain and 10 fingers, tissue paper.

1). Plug out ur ram from pc. Safely (dont break the stick)

2). Now take a cleaning agent (i used water of tomato)

3). Then apply the cleaning agent on ram's bottom, on the golden strips (dont apply on upper part)

4). Now rub it with rubber.

5). Now wipe out the cleaning agent by a tissue paper (i used a newspaper)

6). Now plug the ram into pc and start

Ram will start working.

keep cracking

RAM HISTORY

Early computers used relays, mechanical counters^[ or delay lines for main memory functions. Ultrasonic delay lines could only reproduce data in the order it was written. Drum memorycould be expanded at relatively low cost but efficient retrieval of memory items required knowledge of the physical layout of the drum to optimize speed. Latches built out of vacuum tube triodes, and later, out of discrete transistors, were used for smaller and faster memories such as registers. Such registers were relatively large and too costly to use for large amounts of data; generally only a few dozen or few hundred bits of such memory could be provided.

The first practical form of random-access memory was the Williams tube starting in 1947. It stored data as electrically charged spots on the face of a cathode ray tube. Since the electron beam of the CRT could read and write the spots on the tube in any order, memory was random access. The capacity of the Williams tube was a few hundred to around a thousand bits, but it was much smaller, faster, and more power-efficient than using individual vacuum tube latches. Developed at the University of Manchester in England, the Williams tube provided the medium on which the first electronically stored-memory program was implemented in the Manchester Small-Scale Experimental Machine (SSEM) computer, which first successfully ran a program on 21 June 1948.^[4] In fact, rather than the Williams tube memory being designed for the SSEM, the SSEM was a testbed to demonstrate the reliability of the memory.^[5][6]

Magnetic-core memory was invented in 1947 and developed up until the mid-1970s. It became a widespread form of random-access memory, relying on an array of magnetized rings. By changing the sense of each ring's magnetization, data could be stored with one bit stored per ring. Since every ring had a combination of address wires to select and read or write it, access to any memory location in any sequence was possible.

Magnetic core memory was the standard form of memory system until displaced by solid-state memory in integrated circuits, starting in the early 1970s. Robert H. Dennard invented dynamic random-access memory (DRAM) in 1968; this allowed replacement of a 4 or 6-transistor latch circuit by a single transistor for each memory bit, greatly increasing memory density at the cost of volatility. Data was stored in the tiny capacitance of each transistor, and had to be periodically refreshed every few milliseconds before the charge could leak away.

Prior to the development of integrated read-only memory (ROM) circuits, permanent (or read-only) random-access memory was often constructed using diode matrices driven by address decoders, or specially wound core rope memory planes.

Types of RAM

The two widely used forms of modern RAM are static RAM (SRAM) and dynamic RAM (DRAM). In SRAM, a bit of data is stored using the state of a six transistor memory cell. This form of RAM is more expensive to produce, but is generally faster and requires less dynamic power than DRAM. In modern computers, SRAM is often used as cache memory for the CPU. DRAM stores a bit of data using a transistor and capacitor pair, which together comprise a DRAM memory cell. The capacitor holds a high or low charge (1 or 0, respectively), and the transistor acts as a switch that lets the control circuitry on the chip read the capacitor's state of charge or change it. As this form of memory is less expensive to produce than static RAM, it is the predominant form of computer memory used in modern computers.

Both static and dynamic RAM are considered volatile, as their state is lost or reset when power is removed from the system. By contrast, read-only memory (ROM) stores data by permanently enabling or disabling selected transistors, such that the memory cannot be altered. Writeable variants of ROM (such as EEPROM and flash memory) share properties of both ROM and RAM, enabling data to persist without power and to be updated without requiring special equipment. These persistent forms of semiconductor ROM include USB flash drives, memory cards for cameras and portable devices, etc. ECC memory (which can be either SRAM or DRAM) includes special circuitry to detect and/or correct random faults (memory errors) in the stored data, using parity bits or error correction code.

In general, the term RAM refers solely to solid-state memory devices (either DRAM or SRAM), and more specifically the main memory in most computers. In optical storage, the term DVD-RAM is somewhat of a misnomer since, unlike CD-RW or DVD-RW it does not need to be erased before reuse. Nevertheless, a DVD-RAM behaves much like a hard disc drive if somewhat slower.
