The embodiments herein describe a memory device and method for reading and writing data. In one embodiment, a memory device is provided comprising a memory array and first and second data buffers in communication with the memory array. The second data buffer comprises a larger storage capacity than the first data buffer. During a write operation, data is stored in the second data buffer and then stored in the memory array. During a read operation, data is read from the memory array and then stored in the first data buffer but not in the second data buffer. Because the smaller-storage-capacity buffer takes less time to fill than the larger-storage-capacity buffer, there is less of a delay in outputting data from the memory device as compared to memory devices that use a larger-storage-capacity buffer for both read and write operations. Other embodiments are provided, and each of the embodiments can be used alone or in combination with one another.
