Overview

SD / SDIO Card Combo Device IP core is SD memory controller and a SDIO controller with an AHB interface. Combining with the optional NAND Flash Controller IP, the SD/SDIO Combo Device IP provides an integrated SD memory Card solution for designs that utilize NAND flash memory.

The SD Card Combo IP is a full/high-speed card suitable for memory cards and I/O card applications such as WLAN, Bluetooth, and mobile devices with low power consumption. The full-speed card supports SPI, 1-bit, and 4-bit SD transfer modes at a full clock range of 0-50Mhz. The Arasan SD/SDIO Combo Device IP has an AHB interface, which allows the ARM processor to configure the operational registers resided inside the AHB slave core.

To support NAND flash memory, Arasan provides an optional NAND Flash Controller for direct interfacing with the SD Card Combo Controller IP. The Arasan NAND flash controller handles all command, address, and data sequences. It also manages all the hardware protocols and allows the users to access the NAND flash memory simply by reading or writing into the Operational registers. The Arasan NAND flash controller acts as a master or a slave device on the AHB bus.

UFS Goes Mainstream

UniversalFlash Storage (UFS) was created for mobile applications and computer systems requiring high performance and low power consumption. These systems typically use embedded Flash based on the JEDEC standard eMMC. UFS was defined by JEDEC as the evolutionary replacement for eMMC offering significantly higher memory bandwidth. The standard builds on existing standards such as the SCSI command set, the MIPI Alliance M-PHY and UniPro as well as eMMC form factors to simplify adoption and development.

Types of Storages for Computing System-On-Chips

We are living in an age where we generate the same amount of data each year that has been generated since antiquity. Ever wondered how and where these peta /exa/zetta bytes of data are stored?

Virtual Prototyping Platform with Flash Memory

In this paper we will see how the flash memories developed using Carbon Model Studio helps to bring up an ARM® Cortex A7 flash memory sub-system with primary and secondary boot codes. Flash memories system demonstrated here can be used for early boot code and driver development for any CPU based SoC.
