Semiconductor memory is a type of computer memory that uses semiconductor-based technology to store data. It is essential for the operation of electronic devices, including computers, smartphones, and tablets. This memory is faster and more efficient than traditional magnetic storage, allowing for quicker data access and processing. There are two main types of semiconductor memory: volatile memory, which loses its data when power is turned off, and non-volatile memory, which retains data even without power. Common examples of volatile memory include RAM (Random Access Memory), while flash memory is a popular form of non-volatile memory used in USB drives and solid-state drives.
