Does FRAM lose data after a read?
No. FRAM is a nonvolatile storage memory that retains its data even after the power is turned off. Similar to commonly used DRAM (Dynamic Random Access Memory) found in large (main) memories in personal computers, workstations, and non-handheld game-consoles (such as PlayStation and Xbox), FRAM requires a memory refresh after each read. A memory refresh is done because like DRAM, FRAM memory cells require each bit accessed to be re-written in a refresh function. Because FRAM has an inexhaustible write endurance (100 trillion write/read cycles), this is not a practical concern.
