Patent ID: 7298666

Claim:
An input data distribution device for a memory device, the input data distribution device comprising: a decoding section being configured to receive a starting column address signal wherein the starting column address signal is carried by In(N)/In(2) address lines and the decoding section is configured to transmit N address decoded signals wherein each address decoded signal is carried by In(N)/In(2) address lines; N switching sections, each switching section is configured to receive a clock signal, and each switching section is configured to receive N bits of input data, wherein the N switching sections are subdivided into a first sub-group of N/2 switching sections and into a second sub-group of N/2 switching sections, each switching section in the first sub-group is configured to receive one of the address decoded signals transmitted from the decoding section, each switching section in the second sub-group is configured to receive only part of one of the address decoded signals from the decoding section; and N/2 control sections, each control section is configured to receive a burst determination signal wherein the burst determination signal corresponds to either a sequential mode or an interleaving mode, each control section is configured to receive one of the address decoded signals, and each control section is configured to output a control signal to one of the switching sections of the second sub-group in response to the burst determination signal and in response to one of the address decoded signals, wherein each switching section of the first sub-group is configured to exclusively output one bit from among N bits of a coded input/output data signal in response to one of the address decoded signals and in response to the clock signal, wherein each switching section of the second sub-group is configured to exclusively output one bit from among the N-bits of the coded input/output data signal in response to the control signal, in response to one of the address decoded signals, and in response to the clock signal, and wherein the input data distribution device requires at most the clock signal, the burst determination signal and the starting column address signal to coordinate a data distribution operation of transferring the N bits of input data into N bits of input/output data to the memory device.
