A system and method are disclosed for improved memory performance in a mobile device. A mobile device incorporating teachings disclosed herein may include, for example, a central processing unit (CPU) residing on a first chip. The mobile device may also include a memory system residing on a second chip. The memory system may include, for example, a memory controller and at least one type of memory combined in a single multi-chip package. The multi-chip package may effectively internalize higher pin count interfaces interconnecting the memory controller and the at least one type of memory. With some implementations, a high frequency, low pin-count external bus may form at least a portion of a link communicatively coupling the multi-chip package and the CPU. In practice, the high frequency, low pin-count external bus may physically connect to a bus interface residing on the first chip. The bus interface may be communicatively coupled to the CPU via an internal CPU bus also located on the first chip. In operation, the bus interface may provide bus translation between the high frequency, low pin-count external bus, and the internal CPU bus.
