Abstract

For writing, flash memory devices are physically accessed in a page-oriented mode, but such devices are not error-free in operation. According to the invention, when writing information data in a bus write cycle in a sequential manner into flash memory devices assigned to a common data bus, at least one of said flash memory devices is not fed for storage with a current section of said information data. In case an error is occurring while writing a current information data section into a page of a current one of said flash memory devices, said current information data section is written into a non-flash memory. During the following bus write cycle, while the flash memory device containing that defective page is normally idle, that idle time period is used for copying the corresponding stored section of said information data from said non-flash memory to a non-defect page of that flash memory device.
