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.

Claims19

Dependent claims

A method that facilitates storing data associated with a memory, comprising:

transmitting a first subset of data from a memory array to one or more non-volatile memory blocks in the memory;
and
programming the first subset of the data from the one or more non-volatile memory blocks to a first memory location in the memory array and copying a second subset of the data from a second memory location in the memory array to a third memory location in the memory array based in part on transaction bit information, wherein the transaction bit information is identified from a command generated when an application programming interface (API) initiates a transaction to transfer the first subset of the data to the one or more non-volatile memory blocks, the command includes a size of the first subset of the data, a number of write operations associated with the first subset of the data, information associated with the first memory location in the memory array, and other information associated with the third memory location in the memory array, wherein a controller tracks transferring the first subset of the data from the one or more non-volatile memory blocks to the first memory location to allow an interruption in the transferring to resume from a point where the interruption occurred, and wherein a transaction end bit is set and the programming of the first subset of the data to the first memory location is initiated, without waiting for a next subset of data associated with a next program command to be stored in the one or more non-volatile memory blocks, in response to a determination that the transaction to transfer the first subset of the data to the one or more non-volatile memory blocks is complete.

A system persisted on a non-transitory computer-readable medium executed by a processor that facilitates storage of data associated with a memory, comprising:

a transaction buffer component that receives one or more subsets of user data associated with a transaction from a memory array and temporarily stores the one or more subsets of the user data associated with the transaction in one or more non-volatile memory blocks;
and
a controller component that transfers the one or more subsets of the user data from the one or more non-volatile memory blocks to specified memory locations in the memory array and copies one or more other subsets of the user data from initial memory locations in the memory array to other specified memory locations in the memory array based in part on transaction bit information associated with the transaction, wherein the transaction bit information is ascertained from a command generated by an application programming interface (API) when the API initiates a transaction to transfer the one or more subsets of the user data to the one or more non-volatile memory blocks, the command includes a number of write operations necessary to transfer the one or more subsets of the user data from the one or more non-volatile memory blocks to the specified memory locations, and a respective size of each of the one or more subsets of the user data, information associated with the specified memory locations in the memory array, and other information associated with the other specified memory locations in the memory array, wherein the controller component tracks the transfer of the one or more subsets of the user data from the one or more non-volatile memory blocks to the specified memory locations in the memory array to allow an interruption in the transferring to resume from a point where the interruption occurred, and wherein a transaction end bit is set and the transfer of the one or more subsets of the user data from the one or more non-volatile memory blocks to the specified memory locations in the memory array is initiated, without waiting for a next subset of user data associated with a next program command to be stored in the one or more non-volatile memory blocks, in response to a determination that the transaction to transfer the one or more subsets of the user data to the one or more non-volatile memory blocks is complete.
