Abstract
In a digital system having a host, a controller device and at least one flash memory integrated circuit, a method and apparatus for storing location identification information regarding blocks of information within at least one of the flash memory integrated circuits wherein at least two buffers within the at least one of the flash memory integrated circuits are designated as primary and secondary buffers for storing the identification information in the primary buffer until the primary buffer is effectively full and storing additional identification information in the secondary buffer until it is effectively full, swapping buffer designation so that the primary buffer becomes the secondary buffer and the secondary buffer becomes the primary buffer, erasing the effectively-full buffer for re-use and in this manner, continuously swapping storage of identification information between the two buffers.
