7 / 105 page Document Number: 002-00247 Rev. *G Page 7 of 105 S29GL01GT, S29GL512T While in EA mode, only a Program / Erase suspend command or the Status Register Read command will be accepted. All other commands are ignored. Thus, no other ASO may be entered from the EA mode. When an Embedded Algorithm is suspended, the Data Polling ASO is visible until the device has suspended the EA. When the EA is suspended the Data Polling ASO is exited and Flash Array data is available. The Data Polling ASO is reentered when the suspended EA is resumed, until the EA is again suspended or finished. When an Embedded Algorithm is completed, the Data Polling ASO is exited and the device goes to the previous (calling) mode (from which the Embedded Algorithm was started). In ASO mode, one of the remaining overlay address spaces is entered (overlaid on the main Flash Array address map). Only one ASO may be entered at any one time. Commands to the device affect the currently entered ASO. Only certain commands are valid for each ASO. These are listed in the Table 7.1 on page 48, in each ASO related section of the table. The following ASOs have non-volatile data that may be programmed to change 1’s to 0’s: Secure Silicon Region Lock Register Persistent Protection Bits (PPB) Password Only the PPB ASO has non-volatile data that may be erased to change 0’s to 1’s When a program or erase command is issued while one of the non-volatile ASOs is entered, the EA operates on the ASO. The ASO is not readable while the EA is active. When the EA is completed the ASO remains entered and is again readable. Suspend and Resume commands are ignored during an EA operating on any of these ASOs. 2.1 Flash Memory Array The S29GL-T family has uniform sector architecture with a sector size of 128 kB. The following tables show the sector architecture of the different devices. Note: These tables have been condensed to show sector related information for an entire device on a single page Sectors and their address ranges that are not explicitly listed (such as SA1-SA510 on the GL512T) have sectors starting and ending addresses that form the same pattern as all other sectors of that size. For example, all 128 kB sectors have the pattern XXX0000h-XXXFFFFh in x16 and XXX0000h-XXX1FFFF in x8.
