2026 K4B4G1646E-BYMA In Stock & Price Update | DDR3L SDRAM Market Lead Time, Specs & Replacement Solutions Release Date: May 20, 2026 Abstract Global legacy low-power memory market keeps facing tight supply chain pressure throughout 2026. Mainstream memory manufacturers gradually cut down DDR3L production capacity and shift resources to high-generation memory products. As a classic low-power DDR3L memory chip launched by Samsung, K4B4G1646E-BYMA has stopped official mass production, resulting in sharp reduction of allocated sources, extremely long delivery cycles and continuous rising spot market price. In order to solve the urgent material shortage problem for long-cycle industrial equipment and embedded equipment manufacturers, our company officially launches inventory preferential activities for original authentic K4B4G1646E-BYMA, providing sufficient stable in-stock goods, transparent 2026 latest market price and efficient global logistics delivery service, fully meeting sample verification, small batch trial production and large-scale mass production demand of various industrial terminal products. 1. 2026 Market Delivery Cycle & Supply Demand Situation of K4B4G1646E-BYMA Since the beginning of 2026, the overall supply of DDR3L series storage chips in the electronic components industry has been in short supply, and the market supply gap is expanding day by day. As a widely used 4Gb low-power memory, K4B4G1646E-BYMA has been listed as EOL obsolete model by Samsung, and there is no new mass production plan in the follow-up. Affected by the overall capacity adjustment of the semiconductor industry, the official factory standard delivery cycle of K4B4G1646E-BYMA has extended from 8-10 weeks in 2025 to 22-30 weeks in 2026, and the delivery time of large bulk orders is even more than 36 weeks, which seriously restricts the normal production schedule of downstream manufacturers. In terms of market transaction price, affected by the decreasing available spot inventory, the market price of K4B4G1646E-BYMA has increased by 25% to 35% year-on-year, and there is a huge price difference between bulk procurement and scattered small batch procurement. Many manufacturers that take K4B4G1646E-BYMA as the core storage device are facing multiple risks such as production shutdown due to lack of materials, rising comprehensive production costs and uncontrollable project progress. In view of the severe market supply situation, our company has reserved a large number of high-quality original channel inventory of K4B4G1646E-BYMA through global supply chain layout. We launch 2026 time-limited inventory discount activities, aiming to provide stable and cost-effective procurement channels for global electronic manufacturing enterprises, and effectively avoid various risks brought by supply chain fluctuations. 2.
