MBM29DL32XTD/BD
FUNCTIONAL DESCRIPTION
• Simultaneous Operation
MBM29DL32XTD/BD have feature, which is capability of reading data from one bank of memory while a program
or erase operation is in progress in the other bank of memory (simultaneous operation), in addition to the
conventional features (read, program, erase, erase-suspend read, and erase-suspend program). The bank
selection can be selected by bank address (A
The MBM29DL321TD/BD have two banks which contain
The MBM29DL322TD/BD have two banks which contain
The MBM29DL323TD/BD have two banks which contain
The MBM29DL324TD/BD have two banks which contain
The simultaneous operation can not execute multi-function mode in the same bank. Table 10 shows combination
to be possible for simultaneous operation. (Refer to the Figure 11 Back-to-back Read/Write Timing Diagram.)
*: An erase operation may also be supended to read from or program to a sector not being erased.
• Read Mode
The MBM29DL32XTD/BD have two control functions which must be satisfied in order to obtain data at the
outputs. CE is the power control and should be used for a device selection. OE is the output control and should
be used to gate data to the output pins if a device is selected.
Address access time (t
access time (t
enable access time is the delay from the falling edge of OE to valid data at the output pins. (Assuming the
addresses have been stable for at least t
power-up, it is necessary to input hardware reset or to change CE pin from “H” or “L”
