Accelerated in-memory cache with memory array sections having different configurations

Abstract:

An apparatus having a memory array. The memory array having a first section and a second section. The first section of the memory array including a first sub-array of memory cells made up of a first type of memory. The second section of the memory array including a second sub-array of memory cells made up of the first type of memory with a configuration to each memory cell of the second sub-array that is different from the configuration to each cell of the first sub-array. Alternatively, the section can include memory cells made up of a second type of memory that is different from the first type of memory. Either way, the second type of memory or the differently configured first type of memory has memory cells in the second sub-array having less memory latency than each memory cell of the first type of memory in the first sub-array.
