Abstract
A semiconductor system includes a controller configured to count the number of error check scrub (ECS) operations and configured to generate ECS information that includes information with regard to an address at which the ECS operation is to be performed based on the number of ECS operations. The semiconductor system further includes a memory apparatus configured to perform the ECS operation on a region that is selected by the ECS information.
Claims21
A semiconductor system comprising:
- a controller configured to count a number of error check scrub (ECS) operations and configured to generate ECS information comprising information with regard to an address at which the ECS operation is to be performed based on the number of ECS operations;
- and
- a memory apparatus configured to perform the ECS operation on a region that is selected by the ECS information, and
- wherein the controller is configured to store the number of ECS operations before a power-off operation, and output the ECS information that is stored in the controller to the memory apparatus after a start of a boot-up operation.
1 more element
A semiconductor system comprising:
- a controller configured to:
- receive error check scrub (ECS) information from a memory apparatus,
- store the ECS information, and
- generate ECS resume information comprising address information on which an ECS operation is to be performed based on the ECS information;
- and
- a memory apparatus configured to:
- generate the ECS information comprising information with regard to an address at which the ECS operation has been performed based on a command, and
- sequentially perform the ECS operation from a region that is selected by the ECS resume information, and
- wherein the controller is configured to transmit a count request signal to the memory apparatus before an execution of a power-off operation,
- request the ECS information,
- receive and store the ECS information, and
- wherein the controller is configured to output the ECS resume information to the memory apparatus after a start of a boot-up operation.
9 more elements
An error check scrub (ECS) operation method comprising:
- performing, by a memory apparatus, an ECS operation and storing, in a controller, ECS information comprising information with regard to an address at which the ECS operation has been performed before an end of a power-off operation;
- and
- performing, by the memory apparatus, the ECS operation on a selected region, based on the ECS information, after a start of a boot-up operation, and
- wherein the controller is configured to output the ECS information that is stored in the controller to the memory apparatus after the start of the boot-up operation.
1 more element
An error check scrub (ECS) operation method comprising:
- performing, by a memory apparatus, an ECS operation and transmitting, to a controller, ECS information comprising information with regard to an address at which the ECS operation has been performed before an end of a power-off operation;
- and
- outputting, to the memory apparatus, ECS resume information that is generated based on the ECS information stored in the controller and performing the ECS operation after a completion of a boot-up operation of the memory apparatus based on the ECS resume information, and
- wherein the controller is configured to transmit a count request signal to the memory apparatus before an execution of the power-off operation,
- request the ECS information,
- receive and store the ECS information, and
- wherein the controller is configured output the ECS resume information to the memory apparatus after the start of the boot-up operation.
