The device is a 256K Flash memory organized as 32K bytes of 8 bits each. AMD Flash memories offer the most cost-effective and reliable read/write non- volatile random access memory. The Am28F256A is packaged in 32-pin PDIP, PLCC, and TSOP versions. It is designed to be reprogrammed and erased in-system or in standard EPROM programmers. The Am28F256A is erased when shipped from the factory.
1. High performance
2. CMOS low power consumption
3. 100,000 write/erase cycles minimum
4. Embedded Erase Electrical Bulk Chip-Erase
6. On-chip address and data latches
The SAMSUNG e·MMC is an embedded MMC solution designed in a BGA package form. e·MMC operation is identical to a MMC card and therefore is a simple read and write to memory using MMC protocol v4.41 which is a industry standard. e·MMC consists of NAND flash and a MMC controller. 3V supply voltage is required for the NAND area (VDDF) whereas 1.8V or 3V dual supply voltage
(VDD) is supported for the MMC controller. Maximum MMC interface frequency of 52MHz and maximum bus widths of 8 bit are supported. There are several advantages of using e·MMC. It is easy to use as the MMC interface allows easy integration with any microprocessor with MMC host.
Any revision or amendment of NAND is invisible to the host as the embedded MMC controller insulates NAND technology from the host. This leads to faster product development as well as faster times to market.
