Abstract:
1. A method of configuring a memory system having a memory controller, two sets of request lines and at least a first memory, the first memory having two sections and two request ports, the method comprising: determining mode, selected from a first mode, in which the two sets of request lines are used for memory access in the first memory, each via a respective one of the two request ports, to access a respective one of the two sections, and a second mode, in which only a first one of the two sets of request lines is used for memory access in both sections of the first memory and in which a second one of the two sets of request lines is configured for memory access in a second memory; if the second mode is identified from the determining, configuring memory system such that the second one of the two sets of request lines is operatively coupled to the second memory and is not operatively coupled to the first memory, and further, programming the first memory such that a first one of its two request ports coupled to the first set of request lines is configured to provide memory access to the two sections of the first memory; and configuring the memory controller to, in the first mode, send independent memory transaction requests via one of the first and second sets of request lines to the first memory, depending on the section being accessed and in the second mode, send the independent memory transaction request via one of the first and second sets of request lines such that each memory transaction request accessed a respective one of the first and second memories.
