A data path for memory addressable using an addressing scheme based on a minimum addressable unit, such as a byte, having a size (e.g. 8) which is a power of 2, is configured for transferring data between the memory array and a data interface using a transfer storage unit having N bits (e.g. 12), where N is an integer that is not a power of 2. A page buffer and cache in the data path can be configured in unit arrays with N rows, and to transfer data in the transfer storage units from selected N cell columns.
