FUNCTIONAL DESCRIPTION
Simultaneous Operation
MBM29DL16XTE/BE 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
15
to A
19
) with zero latency.
The MBM29DL161TE/BE have two banks which contain
Bank 1 (8KB
×
eight sectors) and Bank 2 (64KB
×
thirty-one sectors).
The MBM29DL162TE/BE have two banks which contain
Bank 1 (8KB
×
eight sectors, 64KB
×
three sectors) and Bank 2 (64KB
×
twenty eight sectors).
The MBM29DL163TE/BE have two banks which contain
Bank 1 (8KB
×
eight sectors, 64KB
×
seven sectors) and Bank 2 (64KB
×
twenty four sectors).
The MBM29DL164TE/BE have two banks which contain
Bank 1 (8KB
×
eight sectors, 64KB
×
fifteen sectors) and Bank 2 (64KB
×
sixteen sectors).
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 Bank-to-bank 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 MBM29DL16XTE/BE 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
ACC
) is equal to the delay from stable addresses to valid output data. The chip enable
access time (t
CE
) is the delay from stable addresses and stable CE to valid data at the output pins. The output
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
ACC
-t
OE
time.) When reading out a data without changing addresses after
power-up, it is necessary to input hardware reset or to change CE pin from “H” or “L”
