Apparatuses and methods for pipelining memory operations with error correction coding are disclosed. A method for pipelining consecutive write mask operations is disclosed wherein a second read operation of a second write mask operation occurs during error correction code calculation of a first write mask operation. The method may further including writing data from the first write mask operation during the error correction code calculation of the second write mask operation. A method for pipelining consecutive operations is disclosed where a first read operation may be cancelled if the first operation is not a write mask operation. An apparatus including a memory having separate global read and write input-output lines is disclosed.

Apparatuses and methods for pipelining memory operations with error correction coding

One example apparatus includes a first circuit configured to receive first and second data words, to correct one or more errors in the first data word, to merge the corrected first data word and the second data word responsive to a control signal to generate a final merged data word, and to provide the final merged data word to a write circuit. The apparatus also includes a second circuit configured to also receive the first and second data words, to preliminarily merge the first and second data words responsive to the control signal to generate an initial merged data word, to generate an initial parity code for the initial merged data word, to correct the initial parity code, and to provide the corrected parity code to the write circuit.
