Abstract: A memory access control method that can prevent a cell hammer phenomenon includes setting at least a part of all the memory cells a safe memory region, and setting the remaining memory cells to a normal memory region. In the safe memory region, some cells set to an enabled state are accessible for data writing or reading, and the remaining cells set to a disabled state are inaccessible. Based on a safe address mapping algorithm, access to all memory cells in the safe memory region is controlled such that access to the enabled memory cells is allowed and access to the disabled memory cells is prevented. The enabled memory cells in the safe memory region are spaced apart from each other by at least one disabled memory cell in a horizontal and/or vertical direction.

Abstract: The present invention provides a transparent acrylonitrile-butadiene-styrene (ABS) resin and a transparent ABS resin composition. Specifically, according to the present invention, a transparent ABS resin and a transparent ABS resin composition, which have excellent transparency and impact resistance, can be provided by minimizing the degree of impregnation of a styrene monomer into a polybutadiene rubber latex while allowing the styrene monomer to constitute a graft shell to thereby effectively form the graft shell. Particularly, according to the present invention, a transparent ABS resin composition having high transparency and impact resistance can be provided, despite applying a reducing agent and Fe ions, which adversely affected the transparency of ABS resin in the prior art, to ABS resin.
