On December 25, 2020, the Jingcun KS3400P SSD controller developed by Xiamen Jingcun Semiconductor Technology Co., Ltd. has completed the adaptation to YMTC 3D TLC NAND, and has successfully passed multiple verifications of compatibility, stability, and reliability. It is expected To achieve mass production next year.


The Jingcun KS3400P controller is a new generation PCIe NVMe Gen3 x4 SSD control chip. It adopts a dual-core CPU and a 4-channel design. Each channel is equipped with 4 NAND Flash channels. It supports the latest NVMe1.4 protocol and has a read and write performance of up to 2.5G/ s and 2.1G/s, designed for mainstream NVMe SSD applications, can be used in mainstream consumer SSDs and small-size terminal solutions, providing customers with high-performance, high-reliability, and cost-effective PCIe NVMe SSD solutions.

After long-term unremitting efforts, Jingcun KS3400P SSD controller passed the MPW tape-out verification and completed the adaptation with YMTC 3D TLC NAND. This marks the increasing maturity of domestic high-end SSD master control, which will be conducive to the improvement of the core competitiveness of domestic SSDs.
