What are the three main operations for flash memory?

The correct choice highlights the fundamental operations performed on flash memory, which are essential for understanding how flash storage technologies function. Page read, Page write, and Block-erase represent the primary mechanisms through which data is managed in flash memory systems.

Flash memory is organized into pages (the smallest unit of writing), and when data needs to be retrieved, the page read operation allows the necessary data to be accessed quickly. In writing data, the page write operation is crucial as it allows new data to be written or existing data to be updated within a specific page. However, it's important to note that flash memory cannot overwrite data in the same way traditional hard drives do; instead, it requires a block-erase operation for deleting data. This operation clears entire blocks of data, making them available for new written pages, which is why it is an integral part of the three main operations for flash memory.

Understanding these operations is critical for those working with flash technologies, as they influence performance, longevity, and data integrity within storage solutions.
