A calculation system comprises a computing device having one or more instruction-controlled processing cores and a memory controller, the memory controller including a cache memory; and a memory circuit coupled to the memory controller via a data bus and an address bus, the memory circuit being adapted to have a first m-bit memory location accessible by a plurality of first addresses provided on the address bus, the calculation device being configured to select, in order to each memory operation accessing the first m-bit memory location, one address among the plurality first addresses.

Methods and devices for bypassing the internal cache of an advanced DRAM memory controller

A computer device comprises a first processor; a plurality of memory circuits, a first one of which comprises one or more other processors; a data bus coupling the first processor to each of the memory circuits, each of the memory circuits having a data port with a width of m bits and the data bus having a width of n bits, n being higher than m, the first processor and/or another circuit being suitable for reading or writing the data value of n bits in the first memory circuit by converting a first address into a plurality of second addresses corresponding to memory locations of m bits in the first memory circuit, and by performing the reading or writing operation of the data value of n bits in the first memory circuit over a plurality of memory access operations.

Computing device within memory processing and narrow data ports

A memory circuit having: a memory array including one or more memory banks; a first processor; and a processor control interface for receiving data processing commands directed to the first processor from a central processor, the processor control interface being adapted to indicate to the central processor when the first processor has finished accessing one or more of the memory banks of the memory array, these memory banks becoming accessible to the central processor.
