The memory cell is the fundamental building block of memory. It can be implemented using different technologies, … See more

Logic circuits without memory cells are called combinational, meaning the output depends only on the present input. But memory is a key element of digital systems. In computers, it allows to store both programs a… See more

On December 11, 1946 Freddie Williams applied for a patent on his cathode-ray tube (CRT) storing device (Williams tube) with 128 40-bit words. It was operational in 1947 and is considered the first practical implementa… See more

The following schematics detail the three most used implementations for memory cells:
• The dynamic random access memory cell (DRAM);
• The static random access memory cel… See more

The storage element of the DRAM memory cell is the capacitor labeled (4) in the diagram above. The charge stored in the capacitor degrades over time, so its value must be refreshed (read and rewritten) periodically… See more
