Patent GB-2317721-A (GB)
Title: Managing Flash memory
Inventor: BOTHWELL LESLIE INNES
IPC: H04M1/724
Filed: 1996-09-30
Abstract: To reduce wear on a write-few Flash memory changes are written to the Flash memory in batches. Changes to be made are held in RAM and written to the Flash memory depending on their number, their priority levels and the time intervals elapsing between receipt of changes by the RAM. The Flash memory manager monitors the number of times that its blocks are erased and can copy data from the most erased block to the least to even up wear since it is likely that the data transferred from the most erased block is likely to be updated often. The Flash memory manager has an interrupt handling routine which operates during erase or write operations. If an erase operation is in progress, it is halted and reading is enabled. If a write operation is in progress, the interrupt is suspended until the current word has been written at which time memory reading is enabled. If more words remain to be written the write operation is resumed with the next word after the interrupt has been processed.
