Abstract: A data storage device includes a non-volatile memory and a controller operationally coupled to the non-volatile memory. The controller is configured to access information stored at the non-volatile memory. The information includes a user data portion and an error correcting code (ECC) portion corresponding to the user data portion. The controller is further configured to modify the ECC portion in response to an error rate associated with the information exceeding a threshold. The one or more ECC parameters are modified without erasing or re-programming the user data portion.

Abstract: A storage device includes non-volatile memory and a controller. A method performed in the data storage device includes sending an instruction to a host device to cause the host device to perform one or more specified computations. The method further includes receiving a response from the host device. The response is based on execution of the one or more specified computations.
