Methods for accessing memory in a two-dimensional main memory having a plurality of memory slices

摘要

In one embodiment of the invention, a memory module is disclosed including a printed circuit board with an edge connector; an address controller coupled to the printed circuit board; and a plurality of memory slices. Each of the plurality of memory slices of the memory module includes one or more memory integrated circuits coupled to the printed circuit board, and a slave memory controller coupled to the printed circuit board and the one or more memory integrated circuits. The slave memory controller receives memory access requests for the memory module from the address controller. The slave memory controller selectively activates one or more of the one or more memory integrated circuits in the respective memory slice in response to the address received from the address controller to read data from or write data into selected memory locations in the memory integrated circuits.

1. A method for accessing memory in a two-dimensional main memory having a plurality of memory slices, the method comprising:
receiving a plurality of block memory requests to access a main memory having a plurality of memory slices, wherein each memory slice includes a portion of memory of a plurality of memory modules in the two-dimensional main memory; combining the plurality of block memory requests into a compound memory request that can concurrently access data in different memory slices over a plurality of memory modules in the two-dimensional main memory; aggregating data together in response to the compound memory request; and transposing data between rows of data for the main memory and columns of data for one or more processors in response to the plurality of block memory requests.
