For the current project that I work on it with my company, The biggest concern is about part allocation. Flash ICs are one of the major components to build SSD and DRAM after the microcontrollers. It happens couple time that I would be able to spec in and qualify a project, But due to the lead time for the Flash ICs is longer than customer request. we have to meet the customer expectation of certain data. The company has enough stock for the major product line, however, it is more problematic for specific or customized solution, which delays the whole project up to 16 weeks sometimes.
