Hybrid D-PCM, A Combination of PCM and DPCM
IEEE Transactions on Communications, 1978After a short review of the basic principles of PCM and DPCM coding it is shown that combining the two methods in one coding system results in a combination of some favorable properties. The hybrid D-PCM system combines the bit-rate reduction of DPCM with a low error sensitivity.

A PCM/ADM and ADM/PCM code converter
IEEE Transactions on Acoustics, Speech, and Signal Processing, 1979In this paper a bidirectional code converter system that converts PCM to ADM and ADM to PCM directly in the digital domain is studied. The particular coding schemes chosen for study are the μ-255 PCM with the rate of 64 kbits/s and the continuously variable slope delta modulation (CVSD) with 32 kbits/s.

HL-PCM: MLC PCM Main Memory with Accelerated Read
IEEE Transactions on Parallel and Distributed Systems, 2017Multi-Level Cell Phase Change Memory (MLC PCM) is a promising candidate technology for DRAM replacement in main memory of modern computers. Despite of its high density and low power advantages, this technology seriously suffers from slow read and write operations.
