Abstract: A memory sub-system configured to execute a read command of a first type using a combine process to read soft bit data and hard bit data from memory cells. For example, a memory device is to: measure signal and noise characteristics of memory cells for the read command; calculate, based on the characteristics, an optimized voltage and two adjacent voltages that have offsets of a same amount from the optimized voltage; read the memory cells for hard bit data using the optimized voltage and for soft bit data using the two adjacent voltages; and transmit, to the processing device, a response including the hard bit data. The soft bit data can be selectively transmitted based on a classification determined from the characteristics. When a read command of a second type is executed, soft bit data is not read; and/or the signal and noise characteristics are not measured.
