Early Read After Write Operation Memory Device, System And Method

A semiconductor memory device comprising:

• a first bank;
• and
• a second bank,
• wherein a read transaction to the first bank is constrained to wait at least a first time interval following a write transaction to the first bank,
• wherein a read transaction to the second bank is constrained to wait at least a second time interval following a write transaction to the first bank,
• wherein the second time interval is less than the first time interval.

A method of operation in an integrated circuit memory device having a first and second memory bank coupled to an interface, the method comprising:

• receiving first control information to access first data;
• receiving second control information to access second data;
• transferring the first data between the first bank and the interface during a first time interval in response to the first control information;
• and
• transferring the second data between the second bank and the interface during a second time interval in response to the second control information,
• wherein the second time interval occurs during at least a portion of the first time interval.

A method of operation in a semiconductor memory device, the method comprising:

• carrying out a first column access in accordance with a first column access time;
• and
• carrying out a second column access,
• wherein the second column access occurs during at least a portion of the first column access time.

An integrated circuit memory device comprising:

• an interface;
• a first plurality of memory banks;
• a second plurality of memory banks;
• and
• a circuit to transfer first and second data,
• wherein during a time interval, the first data is transferred in response to first control information received at the interface,
• wherein during the time interval, the second data is transferred in response to second control information received at the interface.
