In many applications, designers use flash memory to develop, store, and eventually execute firmware and application code. Design FAQ: Reliability Challenges Emerge With NAND Flash Migrationįlash memory utilization typically depends on the development stage of a product.Design FAQ: Path To High-Performance NAND Flash.Interview: Spansion’s CTO Talks About Embedded Charge Trap NOR Flash.One of the most significant advantages of onboard programming is that it enables design and manufacturing engineers to combine IC testing and programming into a single manufacturing process, which eliminates the need to perform offboard programming of an IC prior to surface-mounting the device. Image size, existing manufacturing infrastructure, system capability, and required programming methods also should be considered in choosing an optimal preprogramming solution.
In-circuit test (ICT), the Joint Test Action Group (JTAG) interface, and external connectors all can be used to program flash devices without impacting manufacturing beat rates.
Yet there are advantages to programming the flash memory after it has been soldered to the PCB. This file type includes high resolution graphics and schematics.įirmware often is preprogrammed into flash memory devices prior to the printed-circuit board’s (PCB) manufacture to maintain high throughput and avoid slowing the manufacturing beat rate.
