9 / 105 page  Document Number: 002-00247 Rev. *G Page 9 of 105 S29GL01GT, S29GL512T Like the Device ID information, CFI information is structured to work with any memory data bus width e. g. x8, x16, x32. The code values are always byte wide but are located at data bus width address boundaries such that incrementing the device address reads successive byte, word, or double word locations with the codes always located in the least significant byte location of the data bus. Because the data bus is word wide each code byte is located in the lower half of each word location and the high order byte is always 0. For further information, please refer to the CFI Specification, Version 1.4 (or later), and the JEDEC publications JEP137-A and JESD68.01. Please contact JEDEC (www.jedec.org) for their standards and the CFI Specification may be found at the Cypress Web site (www.cypress.com/spansionappnotes at the time of this document's publication) or by contacting a local Cypress sales office listed on the web site. 2.3 Status Register ASO The Status Register ASO contains a single word of registered volatile status for Embedded Algorithms. When the Status Register read command is issued, the current status is captured (by the rising edge of WE#) into the register and the ASO is entered. The Status Register content appears on all word locations. The first read access exits the Status Register ASO (with the rising edge of CE# or OE#) and returns to the address space map in use when the Status Register read command was issued. Write commands will not exit the Status Register ASO state. 2.4 Data Polling Status ASO The Data Polling Status ASO contains a single word of volatile memory indicating the progress of an EA. The Data Polling Status ASO is entered immediately following the last write cycle of any command sequence that initiates an EA. Commands that initiate an EA are: Word Program Program Buffer to Flash Chip Erase Sector Erase Erase Resume / Program Resume Program Resume Enhanced Method Blank Check Lock Register Program Password Program PPB Program All PPB Erase Evaluate Erase Status The Data Polling Status word appears at all word locations in the device address space. When an EA is completed the Data Polling Status ASO is exited and the device address space returns to the address map mode where the EA was started. 2.5 Secure Silicon Region ASO The Secure Silicon Region (SSR) provides an extra memory area that can be programmed once and permanently protected from further changes, i. e., it is a One Time Program (OTP) area. The SSR is 2048 bytes in length. It consists of 512 bytes for Factory Locked Secure Silicon Region (SSR0), 1024 bytes for Customer Locked Secure Silicon Regions (SSR1 and SSR2), and 512 bytes for Customer Locked Secure Silicon Region with Read password (SSR3). SSR0 is shipped locked, preventing further programming. SSR1 and SSR2 are OTP with each having separate lock bits and once locked no further programming is allowed for that region. SSR3 is an OTP and requires a SSR3 password to read or program that region. Once SSR3 is locked no further programming is allowed for that region. |
