How memory cores work

The magnetic ring (magnetic core) is magnetic or non-magnetic to represent the bits of 1 or 0, and a long series of 1 or 0 combinations represent the information to be stored. Magnetic core memory is a type of random access memory that acts as the main memory in a computer.
Performance characteristics
Compared with vacuum tubes, the magnetic core memory saves power and does not have the lifespan problem of vacuum tubes. When computers entered the semiconductor era, there was still a considerable period of time when magnetic core memory continued to play the role of main memory. And because the magnetic core memory is a non-volatile memory (Non-volatile Memory), one of its features is that even if the machine crashes or the power supply is interrupted, as long as there is no wrong write signal, it can still retain its content.

Crystal oscillators are used in more and more communication equipment. At the same time, with the development of technology, the types of quartz crystal oscillators are increasing. Therefore, many users are paying attention to how to choose the parameters and types of crystal oscillators. Let's talk about three directions to determine your... Crystal oscillator type.

Memory core development history

One of the important contributions to the magnetic core memory is Dr. Wang An, who invented the write-after-read cycle, which solved a major problem in the application of magnetic cores, that is, reading at the same time The problem of erasing memory without retaining data was later obtained related patents.

Analog (meta) device definition

2022-08-17

Analog (meta)device: A (meta)device that processes analog signals. (waiting for a more precise definition). Analog: Continuous signals are called analog. Specifically, it refers to a quantity that changes continuously within a certain range, that is, it can take any value within a certain range (domain of definition).
