Write buffer flush techniques

Abstract

Methods, systems, and devices for write buffer flush techniques are described. A memory system may be triggered to flush (e.g., transfer, write) data from a volatile memory device to a non-volatile memory device of the memory system. The memory system may support flushing data to blocks including single level cells (SLCs) or blocks including multiple-level memory cells. The memory system may determine whether a quantity of the data to be flushed satisfies a threshold quantity of data. If the quantity of data fails to satisfy the threshold quantity of data, the memory system may flush the data to a block including SLCs, which may be referred to as a small chunk SLC cursor. The SLC cursor may temporarily store the flushed data, such as at least until the threshold quantity of data is satisfied in the volatile memory device and/or to data recovery in case of a power loss event.
