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.

The History SanDisk

SanDisk is a name ubiquitous in the world of technology, which began its life back in 1988 when Eli Harari, Jack Yuan and Sanjay Mehrotra got together to form the company, with its Headquarters in California. This trio were responsible for developing ‘Floating Gate’ technology called EEPROM, which represented something of a breakthrough in semiconductor hardware.

12 years after its inception the company was joined by the Toshiba Corporation in researching new types of semiconductor for the digital camera market.

The Mobile Phone Boom
Around 2003 to 2004, the mobile phone industry was going through a major boom time and Sandisk were a major part of the expansion. As the capabilities of mobile devices increased, their need for expanded memory became ever greater. From memory cards able to store just a few hundred megabytes at the beginning, the technology advanced to such a degree that in a few short years, they were able to cram in 10s or even 100s of Gigabytes into the same space.

Acquisitions
Over the next few years, Sandisk made a number of acquisitions which strengthened their hand in the semiconductor market. From 2005 to 2014, the company acquired:

  • Matrix Semiconductor
  • M-Systems
  • Pilant Technology (a manufacturer of SSD technology)
  • FlashSoft
  • Schooner Information Technology (Developer of Membrain and SchoonerSQL)
  • SMART Storage Systems (SSD manufacturers for the enterprise market)
  • Fusion-io (producers of flash memory used in Enterprise level data centres)

These acquisitions were made at considerable cost to Sandisk, with the total amount in the region of $5bn, but it placed the company well in the market to make even greater strides in the global permanent and flash storage markets.

Since 2014, Sandisk continued to innovate and launched a number of technological firsts, like the Ultra microSDXC memory card, with a staggering 128 Gigabytes of storage contained within. Around the same time, the company launched the Extreme PRO SDXC, which was the highest capacity SD memory card in existence.

Western Digital Acquisition
Fast forward to 2016 and just a few months after Sandisk launched its ‘InfiniFlash’ technology (an entire new category of ‘all-flash’ storage system) and it entered the high end SSD market, the company was bought out by Western Digital, one of the largest HDD manufacturers in the world for a massive $19bn. 

Since 2005, Sandisk is said to have sold over 2 Billion microSD memory cards around the world, illustrating just how large scale its operation is. The company still operates in the same way under the umbrella of Western Digital, who supports in the subsidiary’s efforts to continue to this day, to innovate in the field of memory hardware.
