  • Page 4: Introduction

    With a form factor measuring 12mm by 18mm by 1.2mm, iNAND is expected to be used in a wide variety of portable devices like mobile phones, pagers, and voice recorders.

  • Page 5: Features

    ►Standard footprint across all capacities Document Scope This document describes the key features and specifications of the SanDisk iNAND as well as the information required to interface it to a host system. Chapter 2 describes the physical and mechanical properties of iNAND, Chapter 3 contains the pins and register overview, and Chapter 4 gives a general overview of the SD protocol.

  • Page 6: Functional Description

    Power management for low power operation Technology Independence The 512-byte sector size of the SanDisk iNAND is the same as that in an IDE magnetic disk drive. To write or read a sector (or multiple sectors), the host software simply issues a read or write command to the card.

  • Page 7: Defect And Error Management

    This is completely transparent to the host and does not consume any user data space. The soft error rate specification for iNAND is much better than the magnetic disk drive specification. In the extremely rare case that a read error does occur, iNAND has innovative algorithms to recover the data.
