Abstract:
1. A method for merging sectors of a flash memory module comprising: receiving multiple sectors, each received sector associated with a current erase block out of multiple (B) erase blocks; accumulating the multiple sectors in a sector buffer, the sector buffer stored in a non-volatile memory module; and merging, upon a completion of at least one merge criterion, received sectors belonging to a same current erase block and at least one additional sector of the current erase block to provide a new erase block; wherein the sector buffer comprises at least 2.times.m erase blocks, wherein m=L.times.K/B, L is the total number of erase blocks, B is the number of sectors in the current erase block, and K is a ratio between a merging operation period and a maximal tolerable single sector write operation period.
