Patent attributes
A variety of applications can include apparatus and/or methods that provide parity data protection to data in a memory system for a limited period of time and not stored as permanent parity data in a non-volatile memory. Parity data can be accumulated in a volatile memory for data programmed via a group of access lies having a specified number of access lines in the group. A read verify can be issued to selected pages after programming finishes at the end of programming via the access lines of the group. With the programming of the data determined to be acceptable at the end of programming via the last of the access lines of the group, the parity data in the volatile memory can be discarded and accumulation can begin for a next group having a specified number of access lines. Additional apparatus, systems, and methods are disclosed.
