How data is read in flash memory?

Data in flash memory is read using a process called electrical tunneling, where a voltage is applied to specific memory cells to access stored charge levels. Each cell consists of floating-gate transistors that hold electrical charges representing binary data (0s and 1s). The memory controller interprets the charge state of these cells to retrieve the stored data. This process allows for quick access to data, making flash memory a popular choice for storage in various devices.
