However, the chip could not be used in the TOI since it required very expensive static RAM to operate fast enough.
22.
Security processors typically store secret key material in static RAM, from which power is removed if the device is tampered with.
23.
It used regular " typed " circuits, an increased system clock of 2 MHz and 1 KB of static RAM as main memory.
24.
SRAM, or static RAM, is a volatile type of memory, meaning that its contents are lost each time the power is switched off.
25.
It is interesting to know the period of time for which a static RAM device will retain data once the power has been removed.
26.
Having fully static RAM and a processor whose clock could be frozen without losing state meant spectacular battery life, measured in weeks or even months.
27.
Meanwhile, VLSI entered the merchant high speed static RAM ( SRAM ) market as they needed a product to drive the semiconductor process technology development.
28.
But I would think you would be able to connect the 8 lowest bits of the databus to the static ram and ground the other 24.
29.
It is also possible for an experienced user to replace the built-in 32 KiB RAM chip with a bigger 128 or 512 KiB static RAM chip.
30.
As a result of the design, this tube was more of a static RAM that did not require refresh cycles, unlike the dynamic RAM Williams tube.
