35), display on the LCD 6 (S36), and each time the backward call key 18b is pressed (S30), the address is reduced by one from the last address containing the data related to the specified subject. While reading information from RAM4
(S37), it is displayed on the LCD 6 (S38). Thus, the operator can confirm whether or not the information is memorized by looking at the individual information such as the mathematical formula displayed on the LCD 6.

Here, if the operator presses the jump key 19 (S39) assuming that the displayed information has already been memorized, CP
U1 stores the address of the information in RAM, omits the subsequent display of the information (S40), and increments the count value of the jump number counter by one (S41),
The process returns to step S29 in preparation for the next reading. Further, when the jump key 19 is not pressed, after the display on the LCD 6, the process immediately returns to step S29. By omitting the subsequent display, useless display of information already memorized by the operator is eliminated, and efficient memorization training can be performed. On the other hand, the read information is L
When the determination key 20 is pressed without pressing the call key 18 while being displayed on the CD 6 (S36, S38) (S3)
1) The CPU 1 causes the LCD 6 to display the number of jumped information (display is omitted) with respect to the total information number stored in the RAM 4 for the subject (S32). This allows the operator to know the overall memorization performance of the subject.

Further, as described in S21 of FIG. 3, it is judged whether or not any mode key other than the memorization confirmation key 17 has been pressed (S33). If the result is affirmative, the process returns to the step S4 (FIG. 3), and no judgment is made. If so, it is determined whether or not the clear key 27 has been pressed in the same manner as described in S22 of FIG. 3 (S34). If the result is affirmative, the process returns to the process of step S24 in preparation for calling a different subject. Step S29 in preparation for calling the subject
Return to. Even when it is determined to be no in the first step S23 in FIG. 4, since it is not the memorization confirmation mode, whether or not any mode key other than the memorization confirmation key 17 is pressed (S42) and the keys other than the mode keys such as the four arithmetic operations are pressed. It is determined whether or not is pressed (S43), and if either of the two determinations is affirmative, the process proceeds to the known process in the conventional portable electronic computer (S44), and it is determined that either is not. If so, step S4 is performed to select the memorization setting mode.
