    Abstract: Systems, apparatuses and methods may provide a way to reduce and or eliminate contention between refresh operations and read/write operations, and a larger page buffer for read/write operations for dynamic random access memory (DRAM) technology. More particularly, systems, apparatuses and methods may provide a way to improve a DRAM to perform read/write operations with section selection. Systems, apparatuses and methods may provide for including additional transfer gates in a DRAM to provide section selection to reduce and or eliminate contention between refresh operations and read/write operations, and a larger page buffer for read/write operations.

    Abstract: In one embodiment, a magnetoresistance random access memory (MRAM) such as a spin transfer torque (STT) random access memory (RAM), for example, has a subarray of bitcells and an electro-magnet positioned adjacent the subarray. A magnetic field is directed through a ferromagnetic device of bitcells of the first subarray to assist in the changing of states of bitcells of the subarray from a first state to a second state in which the ferromagnetic device of the bitcell is changed from one of parallel and anti-parallel polarization to the other of parallel and anti-parallel polarization. Accordingly, the content of the subarray may be readily preset or erased to one of the parallel or anti-parallel state with assistance from an electro-magnet. During a normal write operation, the bits to the other state are written. Other aspects are described herein.

    Abstract: Embodiments include apparatuses, methods, and systems including a circuit which may increase a speed of removal of data stored in a memory cell. In embodiments, the circuit may include a control logic to detect a signal and a boost circuit coupled to the control logic to allow the control logic to disable an operation of the boost circuit in response to detection of the signal. A discharge device may be coupled to the boost circuit to accelerate leakage of a leakage current in response to the detection of the signal. In the embodiment, the leakage current is a leakage current of a memory cell coupled to the discharge device and acceleration of the leakage of the leakage current and the disablement of the operation of the boost circuit may increase a speed of erasure of data in the memory cell. Other embodiments may also be described and claimed.
