Abstract
A system and methodology that can prevent errors during data commit on multicycle pass complete associated with a memory is provided. The system employs a transaction buffer component in the memory that receives and temporarily stores information associated with a transaction. A controller component programs subsets of data to respective memory locations once the entire transaction is completed based on the information stored in the transaction buffer component. Thus, if the transaction is interrupted during the transfer of the user data into the buffer, the data stored in the memory is not affected and can still contain the original data when power is regained. If the data transfer between the transaction buffer component and memory array is interrupted, the controller component can complete the transfer from the point of interruption on regaining power and can avoid partial storage of data.
