What is Memory Interleaving?

• Interleaving allows a system to use multiple memory modules as one.
• Interleaving can only take place between identical memory modules.
• Theoretically, system performance is enhanced because read and write activity occurs nearly simultaneously across the multiple modules in a similar fashion to Hard Drive striping.
• Many Apple Power Macintosh and clone systems support interleaving.
• Although many systems require more than one module at a time, most often they are NOT interleaving. The multiple modules are addressed as one large module, but they're not interleaved. These systems address memory in data path that exceeds the width of the memory module, so the designers use older technology to conserve cost and enhance availability of parts.
