Examples of the present disclosure provide apparatuses and methods for performing signed division operations. An apparatus can include a first group of memory cells coupled to a sense line and to a number of first access lines. The apparatus can include a second group of memory cells coupled to the sense line and to a number of second access lines. The apparatus can include a controller configured to operate sensing circuitry to divide a signed dividend element stored in the first group of memory cells by a signed divisor element stored in the second group of memory cells by performing a number of operations.

An instruction to perform a shift and divide operation is executed. The executing includes shifting a value in a specified direction by a selected amount to provide a dividend, the selected amount being user-defined. The dividend is divided by a divisor to obtain a quotient. At least a subset of the quotient is selected as a result. The result is to be used in processing within the computing environment.

A data writing method is provided. The method includes writing a first write data into a first physical sub-unit in a storage device according to a first write command; recording a first meta data corresponding to the first write data into the storage device; writing a second write data into a second physical sub-unit in the storage device; recording a second meta data corresponding to the second write data into the storage device. A second write identification code of the second meta data is set to be different from a first write identification code of the first meta data if the second physical unit is closely adjacent to the first physical unit and the second write data is written according to the second write command; and whether the second write data is valid or invalid is determined according to the second meta data if a special event occurs.
