F-RAM-Slide3

This slide defines some of the terms used in this tutorial. An automotive infotainment system is an integrated electronic system in a vehicle that provides audio/visual entertainment, vehicle status information, and communication and navigation data. Ferroelectric Random Access Memory, F-RAM, is a fast-write, high-endurance, low-energy non-volatile memory that uses ferroelectric technology to store data. Electrically Erasable Programmable Read-Only Memory, or EEPROM, is a common non-volatile memory that uses floating-gate technology to store data. Page write is a write to fixed-length, contiguous block of memory, as an example, a 128kB block in an EEPROM. Soak time is the time, typically 5 ms, required to complete an EEPROM page write after the data is presented at the input buffers. Write endurance is the number of times a non-volatile memory cell can be rewritten before it wears out. Wear leveling is a method to prolong EEPROM Write Endurance that uses up to 8x more EEPROM capacity and a software algorithm to move storage to unused memory addresses when the Write Endurance limit on the active addresses is reached. AEC-Q 100 is a quality standard defined by the Automotive Electronics Council used to verify the reliability of ICs and to qualify them for automotive applications.
