A memory device is described that is capable of expanding an amount of storage capacity available to a host computer without requiring a user to purchase a new, higher capacity memory device that may be bulky and expensive. The memory device includes a host connector that allows a host computer access to a memory within the memory device. The memory device also includes a first set of electrical contacts accessible through a top major surface of a memory device housing and a second set of electrical contacts accessible through a bottom major surface of the memory device housing. The first and second sets of electrical contacts allow a device, such as another memory device, to couple to the host computer through the memory device. In this way, the amount of memory available to the host computer can be increased while maintaining a small form factor for each of the devices.
