Abstract

Devices and techniques for data removal marking in a memory device are described herein. A delete command can be received at the memory device. A count of data portions in the delete command can be compared to determine whether the count is below a threshold. In response to determining that the count of data portions is below the threshold, the data portions can be written to a buffer. When a buffer full event is detected, a segment of an L2P data structure can be loaded into working memory of the memory device. Then, each record in the segment of the L2P data structure that has a corresponding entry in the buffer can be updated to mark the data as removable (e.g., invalid).
