Abstract: Methods, systems, and devices for an erase operation for a memory system are described. The memory system may perform, on a block of memory cells, a first portion of an erase operation. After performing the first portion of the erase operation, the memory system may receive a write command to write data to the block of memory cells. In response to receiving the write command, the memory system may determine whether a threshold voltage of the block of memory cells satisfies a threshold. In response to determining the that the threshold voltage satisfies the threshold, the memory system may perform a second portion of the erase operation on the block of memory cells. As such, the memory system may write the data to the block of memory cells in response to performing the second portion of the erase operation.

Abstract: Methods, systems, and devices for resuming write operation after suspension are described. A memory system may be configured to determine an upper limit of a threshold voltage of a page of a block at which a performance of a write operation was suspended based at least in part on an indication to resume the performance of the write operation that was previously suspended at a memory system; determine a difference between a first quantity of a first logic state stored in the page and a second quantity of the first logic state associated with an unsuspended write operation based at least in part on determining the upper limit of the threshold voltage; and resume the performance of the write operation based at least in part on determining the difference between the first quantity of the first logic state and the second quantity of the first logic state.
