Many Hackaday readers will be familiar with the term “core memory”, likely thanks to its close association with the Apollo Guidance Computer. But knowing that the technology existed at one ...

As manufacturing technology improves, the price of magnetic core memory, which was a few dollars per bit (about 1000 yen), drops rapidly to a few cents (several tens of yen), and by 1970 It is ...

Enter magnetic-core memory (Opens in a new window), the first non-volatile random-access memory (RAM). Magnetic-core memory reads and writes data by setting the magnetism of very small (2mm-wide ...

That’s an example of magnetic core based logic devices, a class that Ken Olsen (founder of DEC) treated in his MIT thesis. So while interesting, and technology that was occasionally used into the ...

Proteins produce nano-magnetic computer memory. ... Hollow core. Apoferritin proteins are spherical and measure 12 nanometres in diameter, with an eight nanometre hollow core.

The AGC, like most computers of the 1960s, used magnetic core memory, storing each bit in a tiny magnetized ferrite ring. Since core memory was fairly bulky, the AGC had just 2K words ...

Diagram of a 4×4 plane of magnetic core memory in an X/Y line coincident-current setup. X and Y are drive lines, S is sense, Z is inhibit. Arrows indicate the direction of current for writing.

The RAMAC’s memory consisted of a magnetic process drum that ran at 6,000 rpm. A separate magnetic core memory unit synchronized the I/O flow in and out of the RAM.

When the Altair computer kit arrived in 1975, it came with a 1-kbyte memory board, and extra 1-kbyte board kits cost $176. A 4-kbyte board in kit form cost $264. The Altair's 8080 processor could ...

For the vast majority of us, computer memory is a somewhat abstract idea. Whether you’re declaring a variable in Python or setting a register in Verilog, the data goes — somewhere &#821… ...
