Abstract
A system may consist of a network controller connected between a non-volatile memory and a host with a disturb module connected to the non-volatile memory. A received data write request from a host may prompt the assignment of a first physical block address in the non-volatile memory to a data block of the data write request with the network controller. The data block and first physical block address can each be characterized with the disturb module before the first physical block address is altered to a second block address in the non-volatile memory in response to a disturb strategy generated by the disturb module. The second block address can be selected based on the characterization of the data block and first physical block address with respect to a risk of a disturb condition occurring in the non-volatile memory.
