The host interface of an SSD refers to the physical connector and the signaling methods used to communicate between the SSD and the host system. This interface is managed by the SSD's controller and is often similar to those found in traditional hard disk drives (HDDs).
Flash memory is an electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for the NOR and NAND logic gates. Both use the same cell design, consisting of floating-gate MOSFETs. They differ at the circuit level depending on ...
An illustration of the write amplification phenomenon in flash-based storage devices. Over time, advancements in central processing unit (CPU) speed has driven innovation in secondary storage technology. [7] One such innovation, flash memory, is a non-volatile storage medium that can be electrically erased and reprogrammed.
Non-volatile memory typically refers to storage in memory chips, which store data in floating-gate memory cells consisting of floating-gate MOSFETs (metal–oxide–semiconductor field-effect transistors), including flash memory storage such as NAND flash and solid-state drives (SSD).
USB flash drive: Various USB 1.1/2.0/3.0/3.1 2000/2001 1 TB+ (not to scale) Universally compatible across most non-mobile computer platforms, their greater size suits them better to file transfer/storage instead of use in portable devices
The term solid-state became popular at the beginning of the semiconductor era in the 1960s to distinguish this new technology. A semiconductor device works by controlling an electric current consisting of electrons or holes moving within a solid crystalline piece of semiconducting material such as silicon, while the thermionic vacuum tubes it replaced worked by controlling a current of ...
