(2.4) Interleaved Memory: Idea: Divide the memory into independent modules to allow simultaneous access to several words in different modules (interleaving). • Efficiency condition: references to memory modules are distributed equitably, with a distribution key. • Ideal Location: The width of the memory access band is multiplied by # d modules. • Total Memory = N = 2n words / / No. of Modules = M = 2m. Schemes – There are 2 schemes, and with either, M parallel words can be obtained with each
