Abstract
Memory devices and systems with on-die data transfer capability, and associated methods, are disclosed herein. In one embodiment, a memory device includes an array of memory cells and a plurality of input/output lines operably connecting the array to data pads of the device. In some embodiments, the memory device can further include a global cache and/or a local cache. The memory device can be configured to internally transfer data stored at a first location in the array to a second location in the array without outputting the data from the memory device. To transfer the data, the memory device can copy data on one row of memory cells to another row of memory cells, directly write data to the second location from the first location using data read/write lines of the input/output lines, and/or read the data into and out of the global cache and/or the local cache.
