Abstract:
In an aspect of the subject matter, a “full” amount of the flash cache (e.g., storage cells) is initially utilized to store data i.e., substantially all of the storage space of the flash cache may be designated to store user data, with the remaining storage space designated to store ECC information (e.g., parity bits) associated with a predefined ECC algorithm utilized to encode the user data. When a bit errors associated with the user data reaches a predefined threshold value, the storage space of the flash cache may transition to store less user data so as to accommodate the space needed to store ECC information associated with a stronger ECC algorithm. The storage space of the flash cache designated to store user data is reduced, while the storage space designated to store ECC information is increased to accommodate the stronger ECC algorithm.
