RAM Revolution

(get ready, yeah)

Random Access Memory, keeping it fast From magnetic cores to the silicon

cast Write it and read it,

the speed of the spark We keep it moving,

light in the dark

(uh-huh,

let's go)

Back in forty-seven, Williams tubes were on the scene

Store a tiny kilobit inside a cathode screen Then came magnetic cores,

weaving wires through the rings Holding states of one and zero,

heavy copper-wound things Until Dennard designed the dynamic cell of DRAM One

single transistor, changing up the whole plan (yeah,

DRAM!)

Asynchronous beats had to synchronize soon Every clock cycle keeping pace with

the tune SDRAM stepped up,

matching the beat Pushing the flow,

raising the heat (bounce,

bounce)

Random Access Memory, keeping it fast From magnetic cores to the silicon

cast Write it and read it,

the speed of the spark We keep it moving,

light in the dark

(uh-huh,

let's go)

Then Double Data Rate burst through the gate DDR one,

two, and three, raising the rate On the rise,

on the fall, we transfer the code Lowering the voltage,

lifting the load Now DDR4 and five dominate the board

Gigabytes of bandwidth, processing restored

(fast lane!)

From static to dynamic

From kilobytes to gigs

No physical moving parts Just silicon rigs (shhhhh)

Random Access Memory, keeping it fast From magnetic cores to the silicon

cast Write it and read it,

the speed of the spark We keep it moving,

light in the dark

(everybody bounce, yeah)

Fast access

Always evolving (yeah)
