Modeling and Simulation of Phase Change Memory Using Digital Logic Implementation Approach

Abstract

Phase Change Memory (PCM) adapts to space utilization and bit storage for displaying amorphous or crystalline states. This change of state relies on the nature of the information and its non-volatility period. As is well known Digital Logic operations are influential over memory modeling, this article introduces a Propagative Adaptability Decision Module (PADM) using DL. This module is utilized based on the information non-volatility across overflow and underflow memory conditions. This utilization-based classification induces the digital logic influence by swapping the states that are robust for further propagative adaptability. This means the possible logical combinations of 0’s and 1’s are used for deciding the states of PCM. The logical operations using OR and NOT are used for reducing overflows whereas the AND and NOT combinations are used for preventing underflows. This reduces the volatility show-up in two distinct phases of memory utilization. Therefore, the 0 and 1 combinations are validated for all the logical operations to ensure propagative memory swapping for balancing the overflow and underflow conditions. This process does not mark up the highest 1 or 0 combination individually due to state changes. The proposed module is validated using swapping rate, time, complexity, and overflow conditions.
