However, the fundamentals for Micron did not deteriorate. The company acquired Elpida, bolstering its overall market share. Contrary to market worries, demand for smartphones has yet to weaken. Prices for memory are also stable. Micron is entering a 16 nanometer flash memory development, too. This will enable Micron to be the manufacturer of the world’s smallest flash memory devices for 128-gigabit memory. Production for the memory will begin in the last quarter of this year, and shipment will start in 2014.Negativity by AssociationBroadcom is down for a separate reason.

During the last quarter, the company said that sales for its combo and networking chip were strong. Mobile baseband chip sales were softening, due to competition from Qualcomm (QCOM) and MediaTek (TWSE:2454).Rambus dropped slightly in recent days, but the company is not facing any troubles. Last quarter, the company earned $0.06 per share on revenue of $57.9 million. In June, the company settled and established a patent licensing deal with STMicroelectronics (STM).

Retailers and carriers may boost promotions for devices, helping memory suppliers like Micron Technology.
