Abstract
Embodiments of the disclosure are drawn to apparatuses, systems, and methods for lossy row access counting. Row addresses along a to address bus may be sampled. When the row address is sampled it may be compared to a plurality of stored addresses in a data storage unit. If the sampled address matches one of the stored addresses, a count value associated with that address may be updated in a first direction (such as being increased). Periodically, all of the count values may also be updated in a second direction (for example, decreased).
