Storage Principles of NAND Flash The basic architecture of the smallest unit in solid-state drives is as follows: We know that all information storage in computers ultimately must return to 0 and 1. In principle, as long as the storage unit can provide two or more distinguishable states, it can be used to record data. … Read more
Background Currently, the mainstream media in embedded storage devices used in mobile terminals (here mainly referring to UFS/eMMC, collectively referred to as “embedded storage devices”) is still TLC. However, the higher storage density of QLC has already been productized, for example, some data centers (read-intensive applications) have already deployed QLC storage devices. QLC can bring … Read more
Source: Semi Connect Author: Belle Flash Memory, also known as Flash, is a type of non-volatile memory that represents data using the threshold levels of storage cells. The main technology used in Flash memory cells is the Floating Gate field-effect transistor (see Figure 5-80). The charge on the floating gate determines the threshold of the … Read more
