10 / 20 page Document Number: 002-00483 Rev. *J Page 10 of 20 S34ML08G1 5th ID Data 7.1 Read Parameter Page The device supports the ONFI Read Parameter Page operation, initiated by writing ECh to the command register, followed by an address input of 00h. The command register remains in Parameter Page mode until further commands are issued to it. Table 7.3 explains the parameter fields. Note: For 41nm 2Gb/4Gb Cypress NAND, for a particular condition, the Read Parameter Page command does not give the correct values. To overcome this issue, the host must issue a Reset command before the Read Parameter Page command. Issuance of Reset before the Read Parameter Page command will provide the correct values and will not output 00h values. This does not apply to 48nm 1Gb.
