*NVRAM*
(“non-‘volatile’ random-access memory”)

*DRAM*
(“dynamic random-access memory”)

*SRAM*
(“static random-access memory”)

*VRAM*
(“video random-access memory”)

(to find out how much ‘RAM’ is on your ‘macbook’…)
(from ‘apple dropdown menu’ (at top left of screen)…)
*go to ‘about this mac’*
(our keyboard shortcut –> ‘SHIFT’ + ‘COMMAND’ + ‘M’)
(this brings up a window with a line that displays “memory”…)
(4GB / 1600 MHz / ‘DDR3’)
(for my ‘2012 macbook pro’)
(click on ‘system report’)
(select ‘memory’ from ‘left-hand list’)
(this shows you how many ‘memory slots’ you have)
(on ‘2012 macbook pro’ i have 2 slots)
(each with 2GB memory)
(called “BANK 0/DIMM0” + “BANK1/DIMM0”)
(also displays ‘status’ for each slot)
(hopefully lists “OK”)

(‘random-access memory’ is a form of ‘computer data storage’ that stores ‘data’ + ‘machine’ code currently being used)
(a ‘random-access memory device’ allows ‘data items’ to be ‘read’ or ‘written’ in almost the same amount of time irrespective of the ‘physical location’ of ‘data’ inside the ‘memory’)
.
(in contrast, with other ‘direct-access data storage media’…)
such as…
‘hard disks’
CD-RWs’
‘DVD-RWs’
(*older ‘magnetic tapes’ + ‘drum memory’)
(….for these older items, the time required to ‘read’ + ‘write’ data items varies significantly depending on their ‘physical locations’ on the ‘recording medium’, due to ‘mechanical limitations’ such as media ‘rotation speeds’ + ‘arm movement’)
(‘RAM’ contains ‘multiplexing’ + ‘demultiplexing’ circuitry, to connect the ‘data lines’ to the ‘addressed storage’ for ‘reading’ or ‘writing’ the ‘entry’)
(usually more than ‘1 bit’ of ‘storage’ is accessed by the same ‘address’, and ‘RAM devices’ often have ‘multiple data lines’ + are labeled ‘8-bit’ / ’16-bit’ / etc’ devices)
(in today’s ‘technology’, ‘random-access memory’ takes the form of ‘integrated circuits’)
(‘RAM’ is normally associated with ‘volatile’ types of memory (such as ‘DRAM modules’), where ‘stored information’ is lost if ‘power’ is removed, although ‘non-volatile RAM’ has also been developed)
(other types of ‘non-volatile memories’ exist that allow ‘random access’ for ‘read operations’, but either do not allow ‘write operations’ or have other kinds of ‘limitations’ on them)
(these include most types of ‘ROM’ and a type of ‘flash memory’ called NOR-flash)
.
(‘integrated-circuit RAM chips’ came into the ‘market’ in the ‘early 1970s’, with the ‘first commercially available DRAM chip’ (the ‘intel 1103’), introduced in ‘october 1970’)
