There are several nonvolatile memory issues designers face. First is that the highest performance systems require the highest read bandwidth to access program memory. This is very straight forward; if there is a low read bandwidth device, not only will that increase the boot time, but it will also slow the execution of instructions during operation. As an example, a traditional 256 Mb Quad SPI NOR Flash memory device can be considered. These products can have read bandwidth as low as 54 MBps, which significantly slows the system performance. Designers also require low pin count interfaces, typically somewhere on the range of less than 25 pins, in order to reduce system cost. In thinking of a high pin count interface, it actually requires additional signal layers, which drives up the PCB cost as well. In the case of a traditional 256 parallel NOR Flash memory which comes in a traditional 56 pin TSOP package, the package itself is over 280 mm squared. In addition to that taking up a lot of board space, there are multiple control, data, and address pins that need to be routed. Designers also have to have high system reliability. Data corruption due to a single bit soft error cannot be tolerated in a high reliability system, especially those requiring less than one FIT. Traditional Quad SPI NOR Flash memories do not support on chip ECC, nor correct single bit soft errors. Finally, designers also require devices to support higher temperature ranges. As enclosures continue to shrink, it reduces the amount of air flow in the system and requires components to operate at higher temperature ranges. The solution to these issues is Cypress's 256 Mb HyperFlash. HyperFlash solves these issues by providing a DDR mode which can run up to 166 MHz, yield 333 MBps bandwidth, and has a low pin count 24 ball package, which only measures 48 mm squared. HyperFlash shares a common footprint with both Quad SPI and dual QUAD SPI, which simplifies the board layout. HyperFlash also has on chip ECC to provide a FIT rate of less than 0.1 FIT per device with respect to single bit soft error. In addition to all of that, HyperFlash has an extended operating temp range of -40°C to + 125°C. Finally, Cypress offers the 256 Mb HyperFlash for the highest-performance systems; one of the industry’s fastest, low-pin-count NOR Flash Memory with high reliability and extended temperature range.
