What method does an SDHC card use for storing data?

An SDHC (Secure Digital High Capacity) card utilizes modern NAND technology for data storage. This technology is specifically designed for flash memory applications and allows for high-density data storage. NAND flash provides a non-volatile storage solution, meaning that it retains data even when power is removed, which is crucial for SD cards commonly used in cameras, smartphones, and other portable devices.

While the option mentioning reprogrammable memory may suggest that the memory can be written to multiple times, which is a feature of NAND flash, it does not accurately describe the specific method or technology used in SDHC cards. The technology employed in SDHC cards is based on NAND architecture, which includes several variations like SLC (Single-Level Cell), MLC (Multi-Level Cell), TLC (Triple-Level Cell), and QLC (Quad-Level Cell), each optimizing for different performance and storage needs.

Secret Storage does not apply to the operation of SDHC cards, as their functioning is based on established flash memory technology rather than any undisclosed methods. Static memory is typically associated with SRAM (Static Random-Access Memory), which is not applicable for the data retention methods used in SD cards.

Understanding the correct technology helps clarify the broader context of how data is stored and retrieved in various
