Question:

What symptoms of wear will present themselves on Cypress FLASH Memory products?

 

Answer:

A Cypress FLASH memory device that has encountered excessive Program or Erase operations may experience defects, such as preventing a cell or group of cells from programming, erasing or reading.

When such a failure occurs in a cell or cells that contain stored critical data, the loss of that critical data may cause system failure. To assist with prolonging the life expectancy of Cypress FLASH memory products, the use of Cypress's FLASH File System (FFS) software is usually employed. To obtain Cypress's FFS software, registration is required.
