Who Invented RAM?

Random Access Memory or RAM, for short, is the silent hero that helps every PC in the world operate quickly and effectively. This small memory chip or at least the idea behind it has a history that goes back some 75 years and the question of who the credit goes to for inventing it is a little more complicated than it first appears.

The Early Years
In the 1940s, computers only existed in government buildings and were typically the size of a family car and stored a minuscule amount of data by modern standards. Magnetic-core memory, as it was called then, used an array of magnetic rings to store data in simple binary 1s and 0s.

Inventor of the Prototype RAM
In answer to the question of who invented RAM, that accolade would go to Robert Dennard, an American electrical engineer from Terrell, Texas. Still, in its basic form and roughly the size of an A4 hardback textbook, it was Mr. Dennard’s prototype that started it all off.

Patent Pending
Over the next 20 years, the hardware evolved to a point that led to the eventual filing for a patent for the RAM chip, in 1968, by digital pioneer Jay Wright Forrester, working with Scientists at Massachusetts Institute of Technology (MIT) on the problem of limited computer memory.

The patent was for a one-transistor Dynamic Random Access Memory (DRAM) cell, which we know to be quite simple compared to today’s technology, but it was the first of its kind. It replaced magnetic core memory and has gone on to form the basis of every standard memory chip in the world.

1969 Breakthrough
With the first commercial personal computers still some 15 years away, a breakthrough occurred in the late 1960s with the invention of ‘solid state’ memory integrated into computer circuits. Using tiny transistors, it was possible to store significantly more information than ever before. Although much smaller today, the basic principle still remains in current memory modules.

This innovation led to the first 1KB RAM chip being created by ‘Intel’, a company formed by Robert Noyce and Gordon Moore that would go on to become a huge player in the microprocessor world. Microprocessors that are in all PCs used today.

First Personal Computer
In the mid-eighties, the first recognisable personal computers came into being, with vastly improved memory capacities at their core. The first Apple Macintosh personal computer came housing 128KB of memory, a stellar leap in just 10 years. Later that same year, the first 1 megabyte chip comes into being. Things were accelerating fast.

Modern Day
Fast forward to 2016 and the average PC has around a massive 4 Gigabytes of memory to play with. Although vastly superior in capacity, today’s RAM hardware would not exist, had those early pioneers not achieved what they did.

Where will we be in another 5 years, 10 or 25 years? Who knows, but whoever produces the first 1 Petabyte (1k Terabytes) or the first Exabyte (1k Petabytes) memory chip will have done so by standing on the shoulders of the great minds from the last century.

Matching RAM to Your Motherboard

Matching suitable RAM to your motherboard is a fairly straightforward process if you know what you’re doing. Adhere to the following steps and you’ll have the information you need in no time at all.

Determining Your Computer’s RAM Type
By accessing the systems menu on your laptop or desktop PC, you will be able to find out what type of RAM hardware you are currently using. From this window, you will see how much RAM you have installed and if you want to know which version of DDR memory you have (DDR2, DDR3 or DDR4), you can have quick peek inside and it should be printed on the side of the components themselves. Sticking to the type of RAM you already have is advisable, as mixing speeds can lead to performance problems.

Should you be going through the process of trying to upgrade the RAM in your machine, there are other factors to take into consideration such as the maximum memory the motherboard and OS is able to take.

One of the most pivotal factors is the Windows operating system is your computer using. You may not be able to upgrade the memory if you have 4 Gigabytes already and you’re running on a 32 bit version of windows. In this instance, you’re going to have to look at either a new computer or new operating system (OS). If you have the 64 bit version of the OS, you’ll have a minimum of 8 Gigabytes of capacity to play with and will only be limited by the maximum memory of the board itself.

If you are aware of the exact model of motherboard you have why no use the OFFTEK motherboard memory configurator to help you determine the specific upgrade required for your machine.
