Abstract
In an embodiment, a method comprises: obtaining a virtual bus address; translating the virtual bus address to a physical address of a portion of NVM storing first data; determining that the first portion of NVM has been allocated previously; reading the first data from the first portion of NVM; determining whether writing second data to the first portion of the NVM would change one or more bits in the first data; responsive to the determining that a write operation only changes data bits in the first data from 1 to 0, writing the second data over the first data stored in the first portion of NVM; and responsive to the determining that one or more bits in the first data would be flipped from 0 to 1, reallocating the first portion of NVM to a second portion of NVM, copying the first data from the first portion of NVM to the second portion of NVM with the first data modified by the second data.
