Semiconductor memory is a digital electronic semiconductor device used for digital data storage, ... The two basic operations performed by a memory chip are "read", ...
The memory cell is the fundamental building block of memory. It can be implemented using different technologies, such as bipolar, MOS, and other semiconductor devices.It can also be built from magnetic material such as ferrite cores or magnetic bubbles. [1]
The two main types of volatile random-access semiconductor memory are static random-access memory (SRAM) and dynamic random-access memory (DRAM). Non-volatile RAM has also been developed [ 3 ] and other types of non-volatile memories allow random access for read operations, but either do not allow write operations or have other kinds of ...
Modern computer memory is implemented as semiconductor memory, [5] [6] where data is stored within memory cells built from MOS transistors and other components on an integrated circuit. [7] There are two main kinds of semiconductor memory: volatile and non-volatile. Examples of non-volatile memory are flash memory and ROM, PROM, EPROM, and ...
Dynamic random-access memory (dynamic RAM or DRAM) is a type of random-access semiconductor memory that stores each bit of data in a memory cell, usually consisting of a tiny capacitor and a transistor, both typically based on metal–oxide–semiconductor (MOS) technology. While most DRAM memory cell designs use a capacitor and transistor ...
Typical DRAM memory operations involve three phases: bitline precharge, row access, column access. Row access is the heart of a read operation, as it involves the careful sensing of the tiny signals in DRAM memory cells; it is the slowest phase of memory operation.
Semiconductor memory uses semiconductor-based integrated circuit (IC) chips to store information. Data are typically stored in metal–oxide–semiconductor (MOS) memory cells. A semiconductor memory chip may contain millions of memory cells, consisting of tiny MOS field-effect transistors (MOSFETs) and/or MOS capacitors.
F 2 is used as a measurement of area for different parts of a semiconductor device, based on the feature size of a semiconductor manufacturing process. Many semiconductor devices are designed in sections called cells, and each cell represents a small part of the device such as a memory cell to store data.
