Abstract:
Approaches, techniques, and mechanisms are disclosed for improving the performance of memory controllers for memory devices. A system may have a memory controller that interfaces with a memory device to store or retrieve information. When the system needs to retrieve information from the memory device, the memory controller sends an address and a command to instruct the memory device to read the information stored at the address. The memory device reads the information, and after a specific amount of time, the memory device sends the information to the memory controller. According to an embodiment, “dummy” data is sent first prior to the availability of the data read out of the memory devices, while waiting for the requested data to be accessed, and then the actual data is sent immediately following the dummy data. According to an embodiment, a geometry of a memory device has only one column of memory cells that are used to store information. The memory device with only one column in an embodiment does not require decoding of a column address. As such, the read latency of the memory device is significantly reduced.
