5th ID Data

3.16

Read ID2

The device contains an alternate identification mode, initiated by writing 30h-65h-00h to the command register, followed by address

inputs, followed by command 30h. The address for S34MS01G2 will be

00h-02h-02h-00h. The address for S34MS02G2 and S34MS04G2 will be 00h-02h-02h-00h-00h. The ID2 data can then be read

from the device by pulsing RE#. The command register remains in Read ID2 mode until further commands are issued to it. Figure

6.33 on page 58 shows the Read ID2 command sequence. Read ID2 values are all 0xFs, unless specific values are requested when

ordering from Cypress.

3.17

Read ONFI Signature

To retrieve the ONFI signature, the command 90h together with an address of 20h shall be entered (i.e. it is not valid to enter an

address of 00h and read 36 bytes to get the ONFI signature). The ONFI signature is the ASCII encoding of 'ONFI' where 'O' = 4Fh,

'N' = 4Eh, 'F' = 46h, and 'I' = 49h. Reading beyond four bytes yields indeterminate values. Figure 6.34 on page 59 shows the

operation sequence.

3.18

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 host may monitor the R/B# pin or wait for the maximum data transfer time (tR) before reading the

Parameter Page data. The command register remains in Parameter Page mode until further commands are issued to it. If the Status

Register is read to determine when the data is ready, the Read Command (00h) must be issued before starting read cycles. Figure

6.35 on page 59 shows the operation sequence, while Table 3.9 explains the parameter fields.

For x16 devices, the upper eight I/Os are not used and are 0xFF.

Note: For 32nm 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.
