Classification: CPC G  Y | IPC G

Claim 0:
1. A memory module comprising:
a printed-circuit (PC) board having a first side and a second side;
a first set of memory components on the first side of the PC board;
first data-buffer circuitry on the first side of the PC board and connected to the first set of memory components to communicate first data to and from the first set of memory components;
a second set of memory components on the second side of the PC board;
second data-buffer circuitry on the second side of the PC board and connected to the second set of memory components to communicate second data to and from the second set of memory components; and
an address-buffer component on the first side of the PC board, the address-buffer component for reading and steering the first data from the first set of memory components to a memory controller via the first data-buffer circuitry and the second data from the second set of memory components to the memory controller via the second data-buffer circuitry, the address-buffer component comprising:
a primary control interface to receive primary commands and primary addresses from the memory controller; and
logic to selectively interpret the primary commands and the primary addresses and responsively convey:
first secondary commands and first secondary addresses to the first set of memory components;
second secondary commands and second secondary addresses to the second set of memory components;
first data-steering signals to the first data-buffer circuitry on the first side of the PC board to direct the first data from the first set of memory components to the memory controller via the first data-buffer circuitry; and
second data-steering signals to the second data-buffer circuitry on the second side of the PC board to direct the second data from the second set of memory components to the memory controller via the second data-buffer circuitry.
