Toshiba Memory Announces 2nd-Gen Serial Interface NAND

Toshiba Memory America has announced the second generation of SLC NAND flash memory products for embedded applications. The company’s second-generation Serial Interface NAND products support the Serial Peripheral Interface (SPI) and can be used in a variety of applications that require high-speed data transfers. The new Serial Interface NAND line features eight products with power supply voltages of 2.70 to 3.60V and 1.70 to 1.95V.

The new Toshiba products are quoted with faster speeds (i.e., 104MHz to 133MHz) compared to previous generations and feature a new command that loads data for programming in 4-bit (QSPI) mode. Toshiba indicates that the addition of an 8Gb device also brings improved NAND density.
