Memory chip, memory module and method for pseudo-accessing memory bank thereof

A memory module, comprising:

• a printed circuit board;
• a control circuit disposed on the printed circuit board;
• and
• a plurality of memory chips disposed on the printed circuit board and coupled to the control circuit, wherein each of the memory chips comprises:
• a plurality of memory banks;
• a plurality of address pins arranged for receiving a plurality of address signals corresponding to the plurality of memory banks, respectively;
• and
• a pseudo-address determining circuit having a plurality of input terminals and a plurality of output terminals, wherein the plurality of input terminals are coupled to the plurality of address pins, respectively, the plurality of output terminals are coupled to the plurality of memory banks, and the pseudo-address determining circuit generates a pseudo-address table for the plurality of memory banks when the memory chip is powered-up,
• wherein the pseudo-address table has a plurality of pseudo-addresses corresponding to the plurality of memory banks, respectively, and each of the plurality of memory banks is arranged to be accessed according to the corresponding pseudo-address.

A method for pseudo-accessing memory banks of a memory chip, comprising:

• generating a pseudo-address table for memory banks when the memory chip is powered-up, wherein the pseudo-address table is stored in a memory, and each of the plurality of memory banks corresponds to a pseudo-address in the pseudo-address table;
• receiving a control signal with an address signal indicating an intended memory bank that the control signal is about to be sent to;
• determining a pseudo-address according to the address signal indicating an intended memory bank and the pseudo-address table;
• and
• redirecting the control signal to a pseudo memory bank indicated by the pseudo-address.
