  This paper presents a memory assessment of the next-generation Versatile
Video Coding (VVC). The memory analyses are performed adopting as a baseline
the state-of-the-art High-Efficiency Video Coding (HEVC). The goal is to offer
insights and observations of how critical the memory requirements of VVC are
aggravated, compared to HEVC. The adopted methodology consists of two sets of
experiments: (1) an overall memory profiling and (2) an inter-prediction
specific memory analysis. The results obtained in the memory profiling show
that VVC access up to 13.4x more memory than HEVC. Moreover, the
inter-prediction module remains (as in HEVC) the most resource-intensive
operation in the encoder: 60%-90% of the memory requirements. The
inter-prediction specific analysis demonstrates that VVC requires up to 5.3x
more memory accesses than HEVC. Furthermore, our analysis indicates that up to
23% of such growth is due to VVC novel-CU sizes (larger than 64x64).
