Toshiba gives NAND a serial interface for NOR replacement


Toshiba’s latest range of NAND flash memory chips  have a serial interface. The advantage of the serial interface is that  the devices can be controlled with just 6-pins, and this means they can be used as low-pin count SLC NAND flash memory. SLC NAND flash memory is now being used as  a higher capacity alternative to NOR flash memory in some embedded ...

Micron legacy SDR/DDR modules live on at ATP


Micron Technology’s legacy DRAM modules (SDR/DDR) will be manufactured by ATP following a license agreement between the companies. Micron published EOL notices for these SDR and DDR DRAM modules in January 2015 with a Last Time Buy (LTB) in July 2015 and a Last Time Ship (LTS) in January 2016. Taiwan-based ATP will continue to manufacture these DRAM modules specifically for the ...

Atmel EEPROM needs just two pins, one wire


Atmel has designed a self-powered EEPROM which requires only two-pins—a data pin and ground pin – for operation. As the devices are self-powered, there is no need for a power source or Vcc pin, with a parasitic power scheme over the data pin. These single-wire EEPROMs have a specified power standby of 700nA, 200µA for write current, and 80µA for ...

UK firm claims highest density MRAM device


UK-based e2v claims to have created the highest density MRAM device in the industry. The firm uses a stacked-package to create a 32Mbit MRAM-based product in a 54-pin TSOP.  The EV5A16B integrates two 16Mbit MRAM devices from Everspin Technologies. According to e2v, the attraction of MRAM technology is that it can offer SRAM-like 35ns read/write timing but with data retention and ...

Micron introduces terabyte SSD using 20nm flash


Micron Technology has announced a terabyte solid state drive (SSD) which it claims will have quick boot-up and will draw as little as 0.15W during normal operation. The NAND flash drive has a speed of up to 95,000 input/output operations per second. The drive’s sequential speeds reach up to 550Mbyte/s for reads and 500Mbyte/s writes, which maxes out the capabilities of the SATA 6 Gb/s ...
