Abstract
Airborne recce systems universally require nonvolatile storage of recorded data. Both present and next generation designs make use of flash memory chips. Flash memory devices are in high volume use for a variety of commercial products ranging form cellular phones to digital cameras. Fortunately, commercial applications call for increasing capacities and fast write times. These parameters are important to the designer of recce recorders. Of economic necessity COTS devices are used in recorders that must perform in military avionics environments. Concurrently, recording rates are moving to $GTR10Gb/S. Thus to capture imagery for even a few minutes of record time, tactically meaningful solid state recorders will require storage capacities in the 100s of Gbytes. Even with memory chip densities at present day 512Mb, such capacities require thousands of chips. The demands on packaging technology are daunting. This paper will consider the differing flash chip architectures, both available and projected and discuss the impact on recorder architecture and performance. Emerging nonvolatile memory technologies, FeRAM AND MIRAM will be reviewed with regard to their potential use in recce recorders.
