Round 1

Reviewer 1 Report

This paper presents an excellent review for Cell Operation Algorithm for 3D NAND Flash. The authors have done a comprehensive literature review the device operation algorithm and techniques to improve the cell characteristics and reliability in terms of optimization of individual program, read,  erase operation and system level performance.

The reviewer generally suggest the acceptance of this paper. The review of 3D flash memory is necessary and it is a timing topic in this research field.

Only one minor issue is related to the adequate references to related and previous work. The reviewer noticed that there have been several state-of-art system-level optimizations to address thermal, temperature, and process-variation issues in 3D charge-trap flash memory. The authors should cite and include these previous studies in the review. This can further improve the quality of the manuscript.

Reviewer 2 Report

Cell Operation Algorithm for 3D NAND Flash Memory is reviewed in this paper. Minor revision is needed as below. 

On page 2

Line 66: “escapes” seems not appropriate. It should be replaced with e.g. “flows”.

Line 72: “worse” seems not appropriate. It should be replaced with e.g. “reduces”.

Lin 78-79: More explanations are needed for this sentence because the reviewer does not understand what is discussed.

 

On Page 8

Line 315:  More explanations are needed for this sentence because the reviewer does not understand what Chen has done.

 

On Page 13

Line 480:  More explanations are needed for this sentence because the reviewer does not understand what Kim has done.

 

On Page 16

Line 606:  More explanations are needed for this sentence because the reviewer does not understand what GAA effect means.
