Title: Control method for non-volatile semiconductor storage device
Inventor: YAMADA HACHIRO
IPC: G11C16/02
Filed: 1993-10-12
Abstract: PURPOSE:To reduce the number of times of erasing operation by performing additional writing corresponding to rewriting in an unused sector without erasing a whole block when unused sectors having numbers exceeding the required number of sectors at the time of rewriting. CONSTITUTION:When unused sectors are deficient, a block is erased in a step 7, each sector of 0th sector-30th sector of a sector section and each flag of flags F0-F30 of a flag table all are rewritten to '1' indicating 'unwritten', flags of an unused sector (j) of (m) pieces from the leading are rewritten from (1, 1) to (1, 0). In the last step 6, writing operation of a block is finished by writing data in an unused sector. In a read-out operation reading input information, a used sector (i) whose contents are (1, 0) out of flags F0-F30 in the flag table is obtained, and read-out operation can be easily performed by reading out successively from a sector of small number.

IPC: G06F7/485
Filed: 1992-08-28
Abstract: PURPOSE: To prevent determination of the existence of preceding zero from being delayed by shifting the subtraction result of a subtractor in accordance with the leading zero prediction result of a leading zero predictor to execute required shift simultaneously with the completion of full subtraction. CONSTITUTION: In a normalizing device which determines the number of preceding zeros of the operation result from subtraction of an operand B from an operand A, operands A and B are stored in a register 10 and are supplied to a subtractor 70. Simultaneously with the calculation of a difference A-B in the subtractor 70, operands A and B are supplied to a preceding zero predictor 80 which determinates the accurate number of preceding zeros of the subtraction result. A first subtraction result 25 is shifted in a shifter 40 in accordance with a result 85 of the leading zero predictor 80 to output a result 60 directly and accurately normalized without using a normalizing corrector.  The full subtractor 70 is so designed that is supplies a borrow signal 90 to the preceding zero predictor 80 as quickly as possible, and this supply is executed just before the full subtraction result is obtained.
