Review of Research on Storage Development

Abstract

The development of computer external storage has undergone the continuous change of perforated cassettes, tapes, floppy disks, hard disks, optical disks and flash disks. Internal memory has gone through the development of drum storage, Williams tube, mercury delay line, and magnetic core storage, until the emergence of semiconductor memory. Later RAM and ROM were born. RAM was divided into DRAM and SRAM. Due to its structure and cost advantages, DRAM has gradually developed into the widely used DDR series. At the same time, the low-power LPDDR series has also been advancing. At present, with the development of NVRAM technology, non-volatile random access memory with both internal and external storage functions is born. Dual-space storage based on NVRAM combines internal and external storage into one, and large capacity dual-space storage has become the development trend of storage.

Electrode dependence in halide perovskite memories: resistive switching behaviours

“…The first memory concept was realised by Gustav Tauschek in 1932 with the invention of drum memory, which is made up of a huge tube-shaped container with a covering of ferromagnetic elements. 1,2 As system memory develops over time, it ultimately transforms into other types of memory such as delay line memory, 3 magnetic drums and core memory, 4 twister memory, 5 bubble memory, 6,7 and today's frequently applied dynamic random access memory (RAM). 8 Nevertheless, the development of memory storage is necessary to store the data retrieved from the system memory.…”
