## Abstract

An information processing system includes: an application adder that obtain an estimated writing amount that is estimated to be written to a non-volatile memory by an application per unit time; and the application adder, a monitor, and a controller that suppress writing to the non-volatile memory by the application based on the estimated writing amount.

## Claims

### Claim 1

An information processing system comprising:
a memory; and
a processor connected to the memory,
wherein, using the memory, the processor:
obtains an estimated writing amount that is an estimated amount of data to be written to a non-volatile memory by an application per unit time; and
suppresses writing to the non-volatile memory by the application based on the estimated writing amount.

### Claim 2 (depends on 1)

The information processing system according to claim 1,
wherein the processor obtains the estimated writing amount when the application is installed in the information processing system.

### Claim 3 (depends on 1)

The information processing system according to claim 1,
wherein when a writing amount that is an amount of data written to the non-volatile memory by the application per unit time is greater than the estimated writing amount, the processor suppresses the writing.

### Claim 4 (depends on 3)

The information processing system according to claim 3,
wherein the processor suppresses the writing by prohibiting the writing.

### Claim 5 (depends on 3)

The information processing system according to claim 3,
wherein the processor outputs a warning when the writing amount is greater than the estimated writing amount.

### Claim 6 (depends on 3)

The information processing system according to claim 3,
wherein the processor notifies the application that the writing is being suppressed while the writing is being suppressed.

### Claim 7 (depends on 1)

The information processing system according to claim 1,
wherein the processor calculates an estimated lifespan of the non-volatile memory from the estimated writing amount, and when the estimated lifespan is shorter than a target lifespan of the non-volatile memory, the processor suppresses the writing by prohibiting the application from being installed in the information processing system.

### Claim 8 (depends on 7)

The information processing system according to claim 7,
wherein the processor outputs a list of one or more applications that are not prohibited from being installed among a plurality of applications including the application.

### Claim 9 (depends on 7)

The information processing system according to claim 7,
wherein when a writing amount that is an amount of data written to the non-volatile memory per unit time by the application installed is greater than the estimated writing amount, the processor issues, to the application installed, a request for a reduction in the writing amount to the non-volatile memory.

### Claim 10 (depends on 9)

The information processing system according to claim 9,
wherein the processor suppresses the writing when the writing amount is greater than the estimated writing amount and the request for the reduction has been issued.

### Claim 11 (depends on 9)

The information processing system according to claim 9,
wherein the processor uninstalls the application from the information processing system when the writing amount is greater than the estimated writing amount and the request for the reduction has been issued.

### Claim 12

An information processing method performed by a computer, the information processing method comprising:
obtaining an estimated writing amount that is an estimated amount of data to be written to a non-volatile memory by an application per unit time; and
suppressing writing to the non-volatile memory by the application based on the estimated writing amount.
