1951

The first RAM modules to come into the market were created in 1951 and were sold until the late 1960s and early 1970s add something


1968

Robert H. Dennard invented dynamic random-access memory 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 add something


1970

Magnetic core memory was the standard form of memory system until displaced by solid-state memory in integrated circuits, starting in the early 1970s add something


1980

Atari 8-bit family - At the same time, the 400 did not compete technically with some of the newer machines appearing in the early 1980s, which generally came standard with much more RAM and an upgraded keyboard


1983

Apple II series - The Apple II Plus was followed in 1983 by the "'Apple IIe"', a cost-reduced yet more powerful machine that used newer chips to reduce the component count and add new features, such as the display of upper and lowercase letters and a standard 64 kB of RAM.


1985

Atari 8-bit family - The 130XE, released in 1985, increased the memory to 128K of bank-switched RAM.

 

Atari 8-bit family - They were announced in 1985, at the same time as the initial models in the Atari ST series, and visually resembled the Atari ST. Originally intended to be called the 900XLF, the 65XE had 64 KB of RAM and was functionally equivalent to the 800XL minus the PBI connection


1988

Apple II series - An Enhanced IIe with 128 kB of RAM can be considered the minimum requirement for running most Apple II software released after about 1988


1989

Dragon Warrior - The North American localization released in 1989 featured numerous changes, including battery-backed RAM save games , modified character sprites and pseudo-Elizabethan English style dialog


1990

Microprocessor - At the time, it formed part of a nine-chip, 24-bit CPU with three AL1s, but it was later called a microprocessor when, in response to 1990s litigation by Texas Instruments, a demonstration system was constructed where a single AL1 formed part of a courtroom demonstration computer system, together with RAM, ROM, and an input-output device


2006

Since 2006, "Solid-state drives" with capacities exceeding 256 gigabytes and performance far exceeding traditional disks have become available add something


2010

Meizu MX - The first rumors about a successor of the Meizu M9 leaked out in Q4 2010, even before M9's official launch itself, suggesting that a so-called "'M9II"' phone was in development, with a dual-core processor, 4-inch screen and 1 GB of RAM


2011

Expeed - In the Nikon 1 cameras introduced September 2011 it uses 1GByte fast DDR2 RAM packaged in 2x 4Gbit chips

 

BeagleBoard - Announced in the end of October 2011, the BeagleBone is a barebone development board with a Sitara ARM Cortex-A8 processor running at 720 MHz, 256 MB of RAM, two 46-pin expansion connectors, on-chip Ethernet, a microSD slot, and a USB host port and multipurpose device port which includes low-level serial control and JTAG hardware debug connections, so no JTAG emulator is required


2012

Raspberry Pi - On 15 October 2012, the Raspberry Pi foundation announced that new Raspberry Pi model B's would be fitted with instead of RAM.


2013

Sony Xperia Z series - At the CES 2013 in Las Vegas, Sony announced the original Xperia Z. It is a smartphone with a 5-inch FHD screen size, 2GB of RAM, Quad Core processor and water and dust resistance, because of the last, many companies started to make phones with water and dust resistance including Samsung with the Samsung Galaxy S4 Active

 

Sony Xperia Z series - First announced at CES 2013, the Xperia ZR is a mid range smartphone with a 4,55 inch screen, 2GB of RAM, Quad core processor

 

Android version history - KitKat debuted on & Google's Nexus 5 on October 31, 2013, and was optimised to run on a greater range of devices than earlier Android versions, having 512 MB of RAM as a recommended minimum; those improvements were known as "Project Svelte" internally at Google


2014

Samsung Galaxy Camera 2 - Announced at the 2014 Consumer Electronic Show in Las Vegas, Nevada, the Galaxy Camera 2 features Android 4,3 Jelly Bean, 1,6 GHz quad-core chip and 2GB RAM


2015

Asus ZenFone - The ZenFone Zoom was announced at CES 2015 and along with ZenFone 2, it's one of the first phones to offer 4 Gigabytes of RAM

 

Android One - On July 2015 Lava launched the 2nd generation Android One phone with a 1,3 GHz quad-core Mediatek MT6582 processor and 2GB RAM.

 

Moto G (3rd generation) - A Moto G Turbo Edition with a faster eight core Snapdragon 615 processor, 2 GB of RAM, IP67 rating, and Quick Charging was revealed for sale in Mexico, Colombia, and India on 13 November 2015,


2018

MacBook Pro - On July 12, 2018, Apple upgraded the internals of the MacBook Pro, adding the T2 SoC Chip and a True Tone Display as well as adding a six-core processor with up to 32GB of RAM to the 15-inch and a quad-core professor to the 13-inch model
