Abstract
A semiconductor memory device includes: a first bank and a second bank; one or more first data input/output pads disposed at one side of the first bank and used in access to data of the first bank; one or more second data input/output pads disposed at one side of the second bank and used in access to data of the second bank; a first cyclic redundancy code (CRC) generation circuit for generating a first CRC using a plurality of data output from the first bank and outputting the generated first CRC through the first data input/output pads; and a second CRC generation circuit for generating a second CRC using a plurality of data output from the second bank and outputting the generated second CRC through the second data input/output pads.
Claims11
A semiconductor memory device, comprising:
- a first bank and a second bank;
- one or more first data input/output pads disposed at one side of the first bank and used in access to data of the first bank;
- one or more second data input/output pads disposed at one side of the second bank and used in access to data of the second bank;
- a first cyclic redundancy code (CRC) generation circuit for generating a first CRC using a plurality of data output from the first bank and outputting the generated first CRC through the first data input/output pads;
- and
- a second CRC generation circuit for generating a second CRC using a plurality of data output from the second bank and outputting the generated second CRC through the second data input/output pads.
A method for driving a semiconductor memory device having a first bank and a second bank, data of the first bank being accessed through one or more first data input/output pads disposed at one side of the first bank, data of the second bank being accessed through one or more second data input/output pads disposed at one side of the second bank, the method comprising:
- generating a first CRC using first data provided from the first bank;
- generating a second CRC using second data provided from the second bank;
- outputting the first data through the first data input/output pads in response to a data access command;
- outputting the first CRC through the first data input/output pads;
- outputting the second data through the second data input/output pads in response to the data access command;
- and
- outputting the second CRC through the second data input/output pads.
