Abstract: Same sized blocks of data corresponding to a single read/write command are stored in the same memory array of a memory device, but using different formats. A first one of these formats spreads the data in the block across a larger number of memory subarrays (a.k.a., memory array tiles—MATs) than a second format. In this manner, the data blocks stored in the first format can be accessed with lower latency than the blocks stored in the second format because more data can be read from the array simultaneously. In addition, since the data stored in the second format is stored in fewer subarrays, it takes less energy to read a block stored in the second format. Thus, a system may elect, on a data block by data block basis, whether to conserve power or improve speed.
