Abstract
A semiconductor memory device includes a first memory bank and a second memory bank and a common write driver configured to drive write data to an activated memory bank of the first memory bank and the second memory bank. The common write driver of the semiconductor memory device includes a common write control block configured to generate common drive control signals corresponding to write data, and a common write drive block configured to drive transmission lines of a first memory bank or transmission lines of a second memory bank that are selected by a bank selection signal in response to the common drive control signals.
Claims51
A semiconductor memory device, comprising:
- a first memory bank and a second memory bank;
- and
- a common write block configured to drive write data to an activated memory bank of the first memory bank and the second memory bank.
A write driver of a semiconductor memory device, the write driver comprising:
- a common write control block configured to generate common drive control signals corresponding to write data;
- and
- a common write drive block configured to drive one of transmission lines of a first memory bank and transmission lines of a second memory bank that are selected by a bank selection signal in response to the common drive control signals.
A write driver of a semiconductor memory device, the write driver comprising:
- a common write control block configured to generate common drive control signals corresponding to write data;
- a drive selection block configured to receive the common drive control signals and output a first drive control signal and a second drive control signal selectively enabled in response to a bank selection signal;
- a first write drive block configured to drive transmission lines of a first memory bank in response to the first drive control signal;
- and
- a second write drive block configured to drive transmission lines of a second memory bank in response to the second drive control signal.
A write driver of a semiconductor memory device, the write driver comprising:
- a common write control block configured to generate common drive control signals corresponding to write data;
- a first write drive block configured to selectively drive transmission lines of a first memory bank in response to the common drive control signals and a bank selection signal;
- and
- a second write drive block configured to selectively drive transmission lines of a second memory bank in response to the common drive control signals and the bank selection signal.
