1. An apparatus comprising:
- a data line;
a first plurality of sub-blocks coupled to the data line, each sub-block of the first plurality of sub-blocks including memory cell strings;
a second plurality of sub-blocks coupled to the data line, each sub-block of the second plurality of sub-blocks including memory cell strings;
a buffer circuit to receive first information; and
a control unit to store second information in the first plurality of sub-blocks and to store third information in the second plurality of sub-blocks, wherein a value of the second information is based on a value of the first information received at the buffer circuit, and a value of the third information is based on the value of the second information.

Abstract
Some embodiments include apparatuses, and methods of forming and operating the apparatuses. Some of the apparatuses include a conductive line, non-volatile memory cells of a first memory cell type, the non-volatile memory cells coupled in series among each other, and an additional non-volatile memory cell of a second memory cell type coupled to the conductive line and coupled in series with the non-volatile memory cells of the first memory cell type. The second memory cell type is different from the first memory cell type.
